Double aerosol container ( 190   a ) comprising outer vessel ( 11 ), flexible inside bag ( 12 ) accommodated in the outer vessel and valve ( 13 ). The inside bag ( 12 ) is divided by means of middle constricted part ( 71 ) into upper and lower storage parts ( 27, 26 ), and the upper and lower storage parts are shut off from each other by means of partition member ( 72 ) at the constricted part. The valve ( 13 ) is fitted with a communication hole for communicating the upper storage part ( 27 ) with the inside of the inside bag ( 12 ) and flitted with dip tube ( 28 ) communicating with the lower storage part ( 26 ). The upper and lower storage parts ( 27, 26 ) are loaded with first contents (A) and second contents (B), which are different from each other, thereby providing an inside bag type double aerosol product. Two-pack type reactive preparations can be employed as a combination of contents of the double aerosol product The double aerosol product is suitable for use in, for example, a hair dye, an enzyme hair dye, a hair setting agent, an antiphlogistic analgesic, a glow inhibitor, a coolant, a pack agent, a cleansing agent, a shaving foam, a humectant, an antiperspirant, a vitamin or a skin softener.

FIELD OF THE INVENTION

This present invention is related to a container for discharging pluralcontents, a dispenser using the container, and a process for producingthe dispenser.

BACKGROUND ART

Conventionally, as a dispenser for discharging plural contents, atwo-fluid mixing type aerosol product is known in which differentcontents are charged in two aerosol containers respectively. Thesecontainers are bundled and discharging members for a common nozzle aremounted on the stem of the valves. The contents are not mixed beforebeen discharged and mixed for the first time when they are discharged.For example, a two-fluid reaction type hair-dye composed of the firstagent containing oxidation dye and the second agent containing oxidantare charged in each container and mixed in the process of discharging.However, since this type is composed of two bundled containers, thestructure of the discharging member is complicated. More, it isdifficult to activate the valves simultaneously and to operate thevalves equally. Further, because it increases the length in thedirection of coupling, it makes it difficult to grasp the container byhand. Furthermore, since this type needs two containers, the contentsmust be inserted separately. This will result in high cost. Also thiscan result in producing aerosol product with different pressure, due tothe difference of the amount of the propellant charged in eachcontainer. Which means it is difficult to adjust the discharging volumeof the two.

On the other hand, in the U.S. Pat. No. 3,079,150, a dispenser of onecontainer filled with a plurality of contents is disclosed. Thisdispenser has a collapsible inner bag inserted in the outer containerand different kinds of the contents especially gelatinous contentscharged in the inner bag in layers. This dispenser can discharge thecontents continuously in multi-layers, each layer made of differentcontent, (multilayer discharging) at the time of discharging gelatinouscontents from one nozzle or spout. Since it is composed of onecontainer, the structure is simple and it is easy to grasp by hand.Further, since it discharges the contents by a propellant charged in onecontainer, the pressure is equal and the discharging volume of bothcontents can be adjusted easily.

FIG. 3 in the above Patent, discloses an inner bag with a lengthwisefold lines, crimps or ribs, to secure the inner bag to be folded inwardfrom three direction (of four direction). The similar inner bag is alsodisclosed in FIG. 3 and FIG. 4 of the Japanese unexamined PatentApplication No.H08-169482.

The dispenser of the above U.S. Pat. No. 3,079,150 needs to fill theinner bag with a plurality of contents slowly so that the contents arenot mixed, because the upper contents are charged sequentially directlyafter the lower contents are charged into the bag. This makes itdifficult to speed up the charging rate causing low charging efficiency.Further, mutual mixing of contents happens during the storage or thetransportation depending on the contents. In such a case, the usercannot obtain the effectiveness of the active ingredient whendischarged, because reaction of active ingredients of the contents isinduced inside the inner bag. And although the inner bag with crimps inlengthwise direction has an advantage that only a small amount ofresidue remains in the inner bag after discharging all the contentsbecause of the uniform folding of the inner bag, the mixing of thecontents cannot be prevented.

Further in the Japanese unexamined Patent Application No. 2003-40368, adispenser for discharging a plural of contents having a plural ofcylinders in the outer container is disclosed. Because this dispensercomprises two cylinders and two pistons, each content can be storedindividually. The contents can be preserved without been mixed duringthe storage or the transportation. However, it increases the componentparts of the dispenser. More, it is difficult to charge the contentsinto the cylinder when dispenser with only one cylinder is used.

This invention is directed to provide a container for discharging pluralcontents and its manufacturing process which facilitates high speedcharging of contents without mutual mixing of contents and with theleast provability of mixing in storage or transportation. Alsomaintaining an advantage of conventional aerosol products that “thecontents are charged in one container, having simple structure, beingeasy to grasp by hand and easy to adjust the discharging volume becauseof a same pressure.”

SUMMARY OF THE INVENTION

A container for discharging plural contents according to the presentinvention is characterized by comprising; an outer container, acollapsible inner bag having a plural of chambers inserted in the outercontainer, a plural of passages communicating each chamber with anatmosphere, a dispensing valve releasing the passages simultaneously, adischarging member activating the valve, wherein the inner bag issubstantially one bag divided into plural chambers by compartmentelement, and each chamber has at least a collapsible part.

In such a container, it is preferable that the passage allows a flowingof the contents and at least one of the passages has a means to stop theflowing when the valve is closed, and it is more preferable that anopening of at least one of the chambers is closed by the valve. It isfurther preferable that the passage independently communicates eachchamber with the atmosphere.

Further, it is preferable that the inner bag has upper and lowerchambers provided vertically, and an easily closable partitioningisolates the lower chamber from the upper chamber, except for thepassage which communicates the lower chamber with the atmosphere.

In such an easily closable partitioning, a partitioning member engagedon the constriction of size smaller than the opening formed at midway ofthe inner bag to isolate the lower chamber from the upper chamber,except for the passage which communicates the lower chamber with theatmosphere, may be used.

It is preferable that a part of the passage from the lower chamber tothe valve is a tube and penetrates the upper chamber, and it is morepreferable that at least a part of such a tube is placed as to bemovable up and down against the valve housing and/or the partitioning.More, it is preferable that the container further comprises a gasabsorbent provided on outer surface of the inner bag and/or inside ofthe outer container.

A dispenser for dispensing plural contents according to the presentinvention is characterized by comprising; the container described above,contents of two or more different kinds, and a means for pressurizingthe inner bag to discharge the contents, wherein each chamber is filledwith one kind of content. “A means for pressurizing the inner bag”herein referred to includes, a compression air charged in a spacebetween the outer container and the inner bag, a pump to vacuum thecontents charged in the inner bag, and a pump to press the inner bag bypressurizing the space between the inner bag and the outer container.

In such a dispenser, it is preferable that the container has twochambers and each chamber is filled with different kind of content.Further, a capacity ratio of the chambers is from 1:5 to 5:1 and thecontents charged in the chambers are discharged in the same ratio as thecapacity ratio. And the preferred contents contain reactive components,which react and display an effect when the contents are contacted ormixed with each other. It is preferable that the reaction of thereactive components is any one of the reactions selected from the groupconsisting neutralization, hydration, redox-reaction, ion-exchangereaction, dissolution, and decomposition.

Further, in a dispenser having two chambers and two kinds of thecontents, the content charged in one of the chamber may be a first agentof hair-dye containing oxidation dye and the content charged in theother chamber may be a second agent of hair-dye containing oxidant. Whenthe contents of the above are used, it is preferable that the inner baghas upper and lower chamber, the inner bag is formed by blow formingusing synthetic resin with laminated structure having gas-absorbancelayer or gas-barrier layer, the first agent of hair-dye contains amines,and the first agent is charged in the upper chamber and the second agentis charged in the lower chamber. It is more preferable that thedispenser further comprises a means to check the remaining amount of thecontents.

A process for producing dispenser in this present invention is a processfor producing dispenser having a container described above, contents ofdifferent kinds and a propellant charged in the outer container,comprising a steps of; placing the inner bag into the outer container,charging the contents into the chambers after fixing the valve to theouter container, and charging the propellant into a space between theouter container and the inner bag anytime after inserting the inner baginto the outer container.

Further, a process for producing dispenser having container with upperand lower chambers and with a partition to open and close an openingbetween the chambers, comprising a steps of, charging one content intoone chamber, isolating one chamber from the other chamber, charging theother content into the other chamber, fixing the valve to the outercontainer, charging the propellant into a space between the inner bagand the outer container with anytime before fixing the valve to theouter container.

The container for discharging a plural of contents according to presentinvention has an inner bag with a plural of chamber divided bycompartment element. Thereby avoid the mixture of the contents duringthe charging of contents and enables the high speed charging of thecontents, although one content is charged into the one chamber directlyafter the other content is charged into the other chamber subsequently.Therefore the charging efficiency can be increased. Further, the mixtureof the content can be prevented during the storage and thetransportation. So this container can be used for the contents that mustbe first mixed at the time of discharging. This container becomes adispenser by charging the contents into chamber, fixing a means to pressthe inner bag, for example the charging a propellant or a compressionair into the space between the outer container and the inner bag, andfixing the valve to the opening of the outer container for sealing.

A pump to vacuum the contents charged in the inner bag, and a pump topress the inner bag by pressurizing the space may be used for the meansto press the inner bag, other than charging the compression air. In thiscase, a pump integral with valve or separated from valve may be fixedafter charging the contents.

The dispenser of the above may be used by opening or releasing thevalve, or by operating the pump to vacuum or to press the contents. Inthis case, the contents charged in the chamber discharge from the nozzleor the spout fixed to the valve through the passage and the valve,because the chambers and the valve are communicated by the passage. Thecontents are discharge in the mixture or the sheathed form depending onthe viscosity of the content and the resistance of the flow system dueto the structure of the valve or the spout. These dispensed form ofcontent or the dispensing operation are substantially the same with thepreviously mentioned U.S. Pat. No. 3,079,150. So it has a simplestructure and is easy to handle compare to the conventional aerosolproduct with two containers. Further, because all the contents chargedin the inner bag receive same pressure, it is easy to control thedischarging amount of the content.

The phrase “substantially one bag” includes a bag having a plural of thechambers, and a plural of chambers linked or combined as a unit. Thephrase “a dispensing valve releasing the passages simultaneously”includes the valve that release the air-tight passage such as aerosolvalve, the valve that open the passage when user operate the piston suchas pump valve, the valve that open the passage when user presses orgrasp such as the squeeze bottle equipped with the valve, and valve thatrelease the passage closed by a check valve.

Where the container with the passage has a means to stops the flowingwhen the valve is close, it prevent the flow between the chamber and thevalve or between the chambers. Therefore, the dispenser with two liquidreactive contents may be efficiently used until the last without themixing with each other. Especially, when all the passages have saidmeans, flowing of the mixed contents from valve, where the content maybe mixed, to the chambers can be prevented. In a result, the non-reactedcontents may be safely preserved in the chambers, despite of therepeating operation of dispensing small amount.

In case that the opening of at least one of the chambers is closed bythe valve, the passage from the chamber to the valve can be easilysecured. Further, the charging of the contents will be eased, becausethe opening of such a chamber will have same size of diameter with thevalve. The phrase “the opening of the chamber is closed by the valve”includes the opening of the chamber closed by both the valve housing andthe valve mounting cup.

In case that the passage independently communicates each chamber withthe atmosphere, the contents charged in the chamber will not be mixed inthe valve or in the container. Therefore it is easy to control thequality of the content containing reactive component that reacts whenthey contact with each other. More, when the combination of the reactivecomponents that cure or creates the reactant of solid matter at the timeof mixture is used as the contents, this invention may prevent theblocking of the valve or the discharging member by the above.

In such a container of above, where the inner bag has upper and lowerchambers provided vertically, and an easily closable partitioningisolates the lower chamber from the upper chamber, except for thepassage which communicates the lower chamber and the atmosphere, twokinds of contents can be charged in one inner bag. So the structure issimple and handling is easy. The user can isolates the lower chamberfrom the upper chamber except for the passage after the charging of thecontent to the lower chamber. Thereby the content charged into the upperchamber will not contact or mix with the contents charged into the lowerchamber, despite of the high speed charging of the content to the upperchamber. This will result in high efficiency. Further, where thepartitioning is not only easily closed but is free for opening andclosing. The same effect of the above may be earned by closing thepartitioning after opening the partitioning by hand or by pressure ofthe charging process to charge the contents into the lower chamber.

In case of that the inner bag has a constriction of size smaller thanthe opening formed at its midway, and a partitioning member is engagedon the constriction to isolate the lower chamber from the upper chamber,except for the passage which communicates the lower chamber with theatmosphere, the manufacturing of the inner bag will be eased. The innerbag does not need the structure for opening and closing the opening ofthe chambers in itself. This partitioning member, for example, can beeasily attached to the inner bag by previously attached to the dip tubethat is a part of the passage.

Where a part of the passage from the lower chamber to the valve is atube and penetrates the upper chamber, the manufacturing of thecontainer will be ease due to the simplicity of the structure of thecontainer. More, when the tube is corrosion resistance against thecontents, the mixture of the contents due to the corrosion of the tubecan be prevented. Further, when at least a part of the tube is placed asto be movable up and down against the valve housing and/or thepartitioning, it will prevent the tube departing from the partitioningmember due to the deformation of the inner bag during or after thecharging of the contents.

Further, where a container of the above further comprises a gasabsorbent provided on outer surface of the inner bag and/or inside ofthe outer container, a gas formed by decomposition of the contents canbe absorbed efficiently. In such a case, the increasing of the pressuredue to the permeation of the gas through the inner bag and thedegradation of the contents can be prevented. A gas maybe, thedecomposition of the hydrogen peroxide and ammonia gas from the ammonia.

The contents that are charged in a dispenser of the present invention donot mix with each other at the time of charging because it comprises thecontainer written in above. So the charging efficiency of the content ishigh. Further, the contents hardly mix with each other during thestorage and the transportation. More, because the dispenser of thepresent invention has a means to pressure the inner bag, the inner bagcollapse by receiving a force from the outside to the inside. Thisenhances the degree of adhesion between the inner bag and thepartitioning member, which further shuts the lower chamber from theupper chamber. This dispenser is best suit for the configuration likethis.

Where the container has two chambers and these chambers are filled withtwo kinds of contents and a capacity ratio of the chambers is from 1:5to 5:1 and the contents charged in the chambers are discharged in thesame ratio as the capacity ratio, the effect of the planning is easilyaccomplished with no waste left over on the one side. Where the contentscontain reactive components in which react and display an effect whenthe contents are contacted or mixed with each other, the reactivecomponents can be stably conserved and prevent the degradation of thedispenser, because this dispenser comprises the container of the aboveand the contents are supplied in the chambers divided by thepartitioning. Further, where the reaction of the reactive components isany one of the reactions selected from the group consistingneutralization, hydration, redox-reaction, ion-exchange reaction,dissolution, and decomposition, it is more preferable because theseeffects can be displayed from one container.

In case that the content charged in one of the chamber is a first agentof hair-dye containing oxidation dye and the content charged in theother chamber is a second agent of hair-dye containing hydrogenperoxide, the contents display the hair-dye effect when the contents aremixed with each other at the time of discharging from the dispenser. Andbecause the dispenser of the present invention comprises the containerof the above, these unstable contents can be preserved for long periodof time in each chamber without been mixed until it is discharged.

Where the inner bag has upper and lower chamber, and the inner bag isformed by blow forming using synthetic resin with laminated structurehaving gas-absorbance layer or gas-barrier layer, the bottom of theinner bag is formed by gluing the inner surface of the inner bag. So thegas-absorbance layer or a gas-barrier layer does not lie between theinner bag and the outer container at the glued part. In such a case whenthe contents charged in the chambers includes the gas that permeatesthrough the resin of the inner bag, the gas leaks outside at the bottomand the product as a whole deteriorates. Further, although the innerlayer of the inner bag is gas-absorbance layer or gas-barrier layer thegas may leak through the attachment surface. In such a case, when thefirst agent of hair-dye contains amines, and the first agent is chargedin the upper chamber and the second agent is charged in the lowerchamber, the permeation of the gas generated from amines through thebottom of the inner bag can be prevented. Especially, when the amines isammonia, this dispenser can prevent the lowering of the ammoniaconcentration and maintain the pH of the oxidation dye. As a result, theoxidation dye can be stored stably. Further, because the second agent ischarged in the lower chamber the second agent can also be stablypreserve. It prevents the contact reaction of the oxidant especiallyhydrogen peroxide with the metal parts of valve.

Where a means to check the remaining amount of the contents iscomprised, the amount of the contents can be confirmed even the outercontainer is not transparent. So the problem of not acquiring enougheffect of the contents due to running down of the contents supplied inthe dispenser during in use may be prevented.

A process for producing dispenser having any one of a containerdescribed above, different kinds of contents and a propellant charged inthe outer container, has a method of placing the inner bag into theouter container, and charging the contents into the chambers afterfixing the valve to the outer container, can charge both contents toeach chamber without mixing with other contents. The propellant areusually charged anytime before the valve is been fixed to the outercontainer, but when the container has gas-charging valve at the bottomof the outer container the propellant may be charged before or after thecontents are charged into the container after the valve is been fixed.

The dispenser with the inner bag having an upper and lower chambers anda propellant charged in the outer container, comprising, a steps ofcharging one content into one chamber, isolating one chamber from theother chamber, charging the other content into the other chamber, fixingthe valve to the outer container, charging the propellant into a spacebetween the inner bag and the outer container anytime before fixing thevalve to the outer container. This dispenser enables to charge thecontents with high charging rate without mixing the contents with theother. Further, where the evacuation of the air between the outercontainer and the inner bag is carried out before the charging of thepropellant, the preservation of the contents for quite a while may beaccomplish due to the prevention of the contact between the contents andthe oxygen in the air. Further, where the evacuation of the air in eachchamber is carried out before the fixing of the valve by opening thevalve, the stability of the contents greatly increase.

THE PREFERRED EMBODIMENT OF THE PRESENT INVENTION

FIG. 1 shows a figure where a container of the present invention isapplied to an inner bag type double-structured aerosol container. Thedouble-structured aerosol container 1 comprises an outer container (orcontainer body) 11 having rigidity; an inner bag 12 that is held in theouter container and has flexibility; a partitioning member 72 dividingthe inner bag in chambers 27 and 26 into an upper part and a lower part;a valve 13 b attached in an opening of the outer container 11; anengaging member 74 attached to a lower part of the valve; a tube 5 forcommunicating the valve 13 b with a lower chamber 26; and an dischargingmember 2 attached to the valve 13 b.

A conventionally well-known container maybe used as the container 11,which is obtained in a way that metal plates, such as of aluminum and oftin, is formed using reducing work etc. to obtain a cylindrical bodyhaving a bottom, shoulder part and neck part are formed in an upper partby necking processing etc., and a bead 17 is formed in a top end of theneck part by curling processing. Moreover, other materials, such assynthetic resins and resisting pressure glass, may also be adopted.

The inner bag 3 is a cylindrical body having a bottom and comprises abody 3 a of the inner bag that has an upper chamber 27, a lower chamber26, and constriction part 71 intervening between the upper and lowerchambers; a neck part 3 b of the inner bag that is formed at a top endof the body, and that has a flange part formed at a top end; and abottom 3 c of the inner bag for closing a lower end of the body.

The constriction part 71 has a radius smaller than a radius of the body3 a, the upper and lower chambers 27 and 26 are formed being taperingdown toward the constriction part 71. This may easily shrink the upperand lower chambers 27 and 26 with discharge of the contents, and as aresult, may make a residual quantity of the contents smaller. Moreover,a lower part of the lower chamber 26 is formed being tapered so that abottom area may become smaller, which makes accommodation of the innerbag into the container easier.

The partitioning member 72, where a lower side face 4 c of the body istapered down, is closely inserted into the constriction part 71 andcomprises the cylindrical body 4 having a bottom, a flange part 4 aformed being tapered in an upper part of the body, and a cylindricalengaging member 4 b projecting from a top face of the body, where aninner surface of top end is being tapered spreading outside, and fittingin closely with the tube 5. In addition, in the lower side face 4 c, anannular projection part 6 projecting outside in a radial direction andengaging with the constriction part is provided. Engaging of thisannular projection part 6 and the constriction part 71 prevents thepartitioning member 72 to separate from the constriction part 71. Thisengagement seals the lower chamber 26 of the inner bag thoroughly,except for tube 5, when the partition member 72 b is inserted into theconstriction part 71 with the tube 5 being inserted.

A valve 13 b has, as shown in FIG. 5, a mounting cup 45 crimped to thebead 17 of the container 11; a housing 46 held in a center of themounting cup; a stem 47 inserted in the housing 46 so as to be freelymovable in up-and-down direction and having two stem pores 47 a and 47b; a stem rubber 49 a and 49 b fitting with the stem pores 47 a and 47 bwithin the housing; a cylindrical fixing member provided between thestem rubbers and for fixing near a periphery end of each of the stemrubbers; and a spring that always energizes the stem upward.

Such configuration provides to inside of the housing a lower compartment25 a divided by an inner wall of the housing 25, the stem 14, and thelower stem rubber 49 a; and an upper compartment 25 b divided by upperand lower stem rubbers 49 a and 49 b and a fixing member 20.

In addition, the stem 14 has two discharging orifices, and channels 18 aand 18 b in the stem being mutually independent from the dischargingorifice. Each of the channels in those stems is in communication withupper and lower stem holes 47 a and 47 b, respectively, and communicatesto each chamber via the upper and lower compartments 25 a and 25 b.

Referring to FIG. 1, in a lower part of the housing of the container 1there is provided a cylindrical projection part 7, having the tube 5inserted thereto, that is inserted to the engaging member 74. Moreover,a gasket is provided in a lower inner surface of the projection part 7,which provides sealing between the tube 5 and the housing 25, andsimultaneously prevents omission of the tube 5.

The engaging member 74 is fitted to a projection part of a valve, andhas a cylindrical form whose lower opening 8 is tapered open anddownward. When the tube 5 inserted in the partitioning member 72 isequipped to the valve 13 b, the engaging member 74 guides the tip of thetube 5 to the projection part 7 of a lower end of the valve by justadjusting a tip of the tube 5 to contact with a lower opening of theengaging member, making insertion of the tube 5 into the valve easier.

The tube 5 is inserted into the projection part 7 of the housing 46, andis extended below, and is of materials of metal (for example, stainlesssteel) or of synthetic resins having corrosion resistance to contents.Synthetic resin coated layers may be provided on an outer surface and/oron an inner surface of a metal tube. The dispenser product may be fullyconsumed using these configurations, without mixing of the contents witheach other.

The discharging member 2 comprises a valve engaging member 2 b havingtwo communication holes 2 a; two ejecting holes 2 c; and channels 2 d inthe discharging member for communicating the communication hole 2 a withthe ejecting hole 2 c, respectively. The opening of the valve byoperating the discharging member will independently discharges thecontents separately discharged from a stem of the valve, without mixing.

In the present invention, a content A is charged into the lower chamber26 of the inner bag, the partitioning member is inserted into theconstriction part, the lower chamber is isolated except for channels (orpassages), subsequently, a content B is charged into the upper chamber27, an opening of the upper chamber is closed by placing or fitting thevalve on an opening of the inner bag, a propellant C is charged into aspace between the container 11 and the inner bag 12 by under-cupcharging method etc., the valve is fixed to the container, and finally adispenser 1 a may be obtained. A charging valve for propellant may alsobe provided in a bottom of the container 11 etc.

As materials for inner bags of such containers, for example, there maybe used synthetic resins, such as, linear low density polyethylenes(LLDPE), low density polyethylenes (LDPE), high-density polyethylenes(HDPE), polypropylenes (PP), polyethylene terephthalates (PET),polybutylene terephthalates (PBT), polyethylenenaphthalates (PEN),polyacrylonitriles (PAN), ethylene-vinylalcohol copolymers (EvOH),Nylons (NY), polyphenylene sulfides (PPS), polyvinyl chlorides (PVC),polyvinylidence chlorides (PVDC); metallic foils, such as aluminum (Al).When the synthetic resins are used, the resins are molded by a blowmolding method etc. into a cylindrical body having a bottom, and thus aninner bag of the container may be obtained.

As structures of the inner bag, there may be mentioned a monolayerstructure of the synthetic resin, or two or more kinds of laminatedstructures (for example, LDPE/EvOH/LDPE, LDPE/NY/LDPE, etc.), orfurthermore, metallic foils laminated with synthetic resins (forexample, LDPE/Al/LDPE etc.), and each chamber has at least a flexiblepart which deforms by a pressure difference. A thickness of the innerbag is 0.1 through 2.0 mm, and preferably 0.3 through 1.0 mm, inconsideration of easiness of blow molding, or flexibility. In addition,according to contents charged, a thickness of the upper and lowerchambers of the inner bag may arbitrarily be set, for example, athickness of only one chamber may set thicker. Moreover, according tocontents, partially different qualities of materials may be used.Additionally, inner bags may be molded using composite materials.Further, in addition to the synthetic resin, including: volatile rustpreventives, such as, dicyclo hexyl ammonium nitrite, dicyclo hexylammonium caprylate, and cyclohexyl amine carbamate etc.; gas absorbents,such as ferrous oxide; conductive powders, such as carbon black; metalpowders, such as silver and nickel; antistatic agents, such as carbonfiber.

FIG. 2 a and FIG. 2 b show another embodiment where a container of thepresent invention is applied to a double-structured aerosol container 10of inner bag type. The double-structured aerosol container 10 comprisesa container 11 having rigidity; an inner bag 12 having flexibility heldin the container; and a valve 13 (refer to FIG. 2 b) attached in anopening of the container 11. Conventionally well-known containers may beused for the container 11 as in the above-mentioned embodiment.

The inner bag 12 is substantially same as conventional inner bags exceptthat it may be constituted freely openable and closable to have a statethat communicates an upper part with a lower part in a center section 21(FIG. 2 a), and a state that isolates the upper part from the lower part(FIG. 2 b).

Inside of the inner bag 12 is divided into a lower chamber 26 and anupper chamber 27 via a center section 21, in a state where the centersection 21 is closed as shown in FIG. 2 b, upper and lower chambers 27and 26 are mutually almost isolated except for a dip tube 28 provided ina valve 13. A dip tube used in the container having upper and lowerchambers is a part of a passage that communicates the lower chamber withthe valve, and that communicates the lower chamber with exterior (or anatmosphere), and may be of synthetic resins, or metals.

In the embodiment, a configuration freely openable and closable in thecenter section 21 comprises a bendable piece 32 having two or moresheets of inverse-triangled shape connected via bending lines 31 in alower end of an upper cylinder 30; a bendable piece 35 having atriangled shape connected via bending lines 34 in an upper end of alower cylinder 33; and cylindrical parts 36 having cornice shapeprovided between those bendable pieces 32 and 35. Tips of the upperbendable piece 32 and the lower bendable piece 35 are faced to eachother. A upper end of the cylindrical parts 36 having a cornice shape isprovided with a continuous saw-toothed shape via an oblique side of theupper bendable piece 32 having a triangle shape and the bending line 31.Similarly, a lower end is provided with a continuous saw-toothed shapevia an oblique side of the lower bendable piece 35 having a triangleshape and the bending line 34. And in the cylindrical bellows-like part36, a vertical line for connecting tips of upper and lower triangles isset as mountain fold bending line 40, and a vertical line for connectingbases of the upper and lower triangles is set as valley fold bendingline 41. Accordingly, in the cylindrical part 36 having a cornice shape,a mountain fold bending line 40 and a valley fold bending line 41 arealternately arranged, as shown in FIG. 2 c, and FIG. 2 d, which enablethe cylindrical part to be foldable.

In the inner bag 12 thus constituted, when elongated as in FIG. 2 a, thebendable pieces 32 and 35 having a shape of an upper and a lowertriangles are extended downward and upward, the cylindrical cornice part36 presents an opened star-shape, as shown in FIG. 2 c. Accordingly, ithas a large opening in a center and, thereby, the lower chamber 26 ofthe inner bag 12 may be in communication with the upper chamber 27 witha wide area. On the other hand, when the flange 24 of the inner bag 12is pushed down in a vertical direction of the container, or in a statewhere it is contracted in a vertical direction as in FIG. 2 b, after avalve is crimped after charging of contents, the upper bendable piece 32having a triangle shape and the lower bendable piece 35 having atriangle shape are bent inward, respectively, to give a shape where theupper part and the lower part are almost isolated except for a centerpart as shown in FIG. 2 b and FIG. 2 d. Then, those bendable pieces 32and 35 give a folded star shape (FIG. 2 d), while allowing inwarddeformation of the cylindrical cornice part 36, as mentioned above, andthey are almost thickly closed in a vertical direction except for thedip tube 28. Moreover, in FIG. 2 d there is shown a state where aclearance is provided between the upper and lower pieces of thecylindrical part 36, in order to help understanding, but actually, theyare almost stuck firmly to each other. When the cylindrical cornice part36 is shrunk as in FIG. 2 b, the mountain fold bending line 40 is alsovertically compressed, being pulled inward, and they curve inward whilebent in horizontal direction.

The valve 13, as in FIG. 2 b, comprises a mounting cup 45 crimped to abead 17 of the container 11; a housing 46 held in a center of themounting cup; a stem 47 held freely movable in vertical direction in thehousing 46; a spring always energizing the stem upward (not shown); andthe above-mentioned dip tube 28 extending downward from a lower end ofthe housing 46. The valve 13 is substantially same as conventionalvalves, except for comprising a communication hole 48 in communicationwith the upper chamber 27 of the inner bag 12, in a lower part of thehousing 46. That is, the mounting cup 45 has a curved flange 50 crimpedto the bead 17 via the flange 24 and a gasket 49 of the inner bag 12,and cylindrical housing hold part 51 with a bottom for holding thehousing 46. The mounting cup 45 is, for example, of metal plates, suchas aluminum and tinplate.

The housing 46 is a cylindrical type component made of synthetic resins,and a valve rubber (not shown) for opening and closing a stem hole ofthe stem 47 intervenes between a top end and underside of the mountingcup 45. As the stem 47, the spring, and the valve rubber, conventionallywell-known materials may be employable. This housing 46 is incommunication with the lower chamber 26 of the inner bag 12 via a diptube 28, and with an upper part of the upper chamber 27 of the inner bag12 through a communication hole 48. That is, the dip tube 28 and thecommunication hole 48 are a part of passages for communicating betweenan each chamber and an exterior. Adjustment of length and diameter ofthe passages may control a rate of flow from each chamber, and may alsocontrol discharged amount ratio of contents charged into each chamber toan suitable percentage. As the dip tube 28, metals (for example,stainless steel) having high corrosion resistance and non-permeabilityto contents, or synthetic resins may be used, or materials having acoated surface with synthetic resins may preferably be used. Use ofthese materials will prevent the reaction of contents charged in theupper and lower chambers with the dip tube. Thereby, a content in alower part remained in the dip tube 28 and a content in an upper chamber27 of outside of the dip tube 28 may not be permeated through the diptube 28 to be mixed or reacted with each other via the dip tube 28.

Moreover, as valves used for an aerosol product of the presentinvention, there may be used a valve 13 a with a check valve a shown inFIG. 3 a; a valve 13 b shown in FIG. 3 b; a valve 13 c shown in FIG. 3c, and furthermore a valve 13 d shown in FIG. 3 d. A housing 46 a of thevalve 13 a shown in FIG. 3 a has a pair of communication holes 48 a and48 b in a lower end, one communication hole 48 a is in communicationwith the lower chamber 26 of the inner bag through the dip tube 28engaged to the dip tube engaging member 55, and another sidecommunication hole 48 b is in direct communication with the upperchamber 27 of the inner bag 12. A check valve 51 a is provided in anupper part of these communication holes 48 a and 48 b. The check valve51 a is constituted with balls 53 placed in an upper part of thecommunication holes 48 a and 48 b, and springs 52 energized so thatballs 53 may be pushed against the communication hole and as a resultthe communication hole may be closed.

When discharging members, such as an injection button or a spoutinserted in the stem 14, are pushed down and a stem hole 47 a opens,inside of the container communicates with the atmosphere. Contentspushes up the ball 53 currently energized by the spring 52 with an aidof a pressure of a compressed gas charged in an interior space of thecontainer, and thus discharge of contest will be performed from andischarging hole of the discharging member via the stem hole and thestem. However, since the ball 53 is energized downward with the spring52 to close the communication hole in a usual state, the contents mixedwithin the housing 46 a does not flow backward to each chamber. Thus,the check valve 51 allows a flow from each chamber to the valve, andprevents a flow to the chamber from the valve. Thus, return to chamberof the contents once mixed within the housing 46 a can be prevented(refer to FIG. 4 a and FIG. 4 b). In this valve 13 a, contents A and Bcontained in the upper and lower chambers are mixed within the housing46 a of the valve. Accordingly, each passage from each chamber to thepassage holes 48 a and 48 b of the valve are mutually independent, andeach channel from the communication holes 48 a and 48 b to exterior isshared.

The valve 13 b shown in FIG. 3 b has a housing 25; a stem 14 having twostem holes 47 a and 47 b held freely slidable in the housing; stemrubbers 49 a and 49 b fitting with those stem holes 47 a and 47 b withinthe housing; and a cylindrical fixing member 20 provided between thestem rubbers and for fixing near periphery end of each stem rubber. Thisconfiguration provides a lower compartment 25 a divided by an inner wallof the housing 25, the stem 14, and the lower stem rubber 49 a; and anupper compartment 25 b divided by the upper and lower stem rubber 49 aand 49 b and the fixing member 20 in the housing. Moreover, the stem 14has independent passages 18 a and 18 b, and the passages are incommunication with each chamber via the lower and upper compartments 25a and 25 b by the lower and upper stem holes 47 a and 47 b. That is,when the stem 14 is pushed down and the stem holes 47 a and 47 b areopened, the content in the lower chamber passes through the dip tube 28from the lower chamber, and through the communication hole 48 a of alower end of the housing, reaches in the lower compartment 25 a, and isstored therein, and on the other hand, the content in the upper chamberreaches in the upper compartment 25 b through the communication hole 48b, and is stored therein. And these contents further go to a dischargingorifice through the stem holes 47 a and 47 b, and passages 18 a and 18 bin the stem, respectively. Thus, use of this valve 13 b enablessimultaneous discharging, avoiding mixing of the contents of the upperand lower chambers, respectively. That is, use of this valve 13 b canmake each passages that communicates each chamber with the exterior orthe atmosphere independent against the others. Such a configuration isparticularly effective and preferable in following cases: a case wherethe contents in the upper and lower chambers of an aerosol product ofthe present invention may be mixed and reacts with each other to givecuring, heat generation, heat absorption, discoloration, etc.; a casewhere the contents do not react each other but give different colors,respectively; a case where two liquids mixing well, that is, excellentin compatibility, for example, water and alcohol, etc. are incombination; and a case where a combination of contents having a smallspecific gravity difference(see FIG. 5 a, 5 b).

Valve 13 c of FIG. 3 c has one passage in the stem 14, and isconstituted so that each contents may be mixed within the stem 14 afterthe contents are pushed out from each chamber to the stem holes 47 a and47 b through each compartments 25 a and 25 b, respectively. Otherconfigurations are same as of the valve 13 b of FIG. 3 a. Thereby, sincethe contents are mixed within the stem 14, mixed contents do not flowbackwards into the valve, which enables stable preservation of thecontents for long period of time. FIG. 6 a and FIG. 6 b show opening andclosing state of a valve 13 c substantially equivalent to this valve 13c.

Valve 13 d of FIG. 3 d comprises a housing 25; a stem 14 with stem holes47 a held being freely slidable in the housing; a cylindrical middleseal member 20 a inserted between the housing inner wall and the stem; astem rubber 49 a engaged with the stem hole 47 a provided on the middlesealing member; and a mounting cup 49 c for fixing the valve to thecontainer by crimping them to the container. Besides, the housing 25 hascommunication holes 48 a and 48 b in communication with upper and lowerchambers. Thereby there is provided a configuration that the stem hole47 a is usually closed by the stem rubber 49 a, and a content in theupper chamber flowing in via the communication hole 48 b is blocked by aslope of the middle sealing member 20 a and the stem 14, and thecontents does not flow inside of the middle sealing member 20 a. Whenthe stem 14 is pushed down and the stem hole 47 a opens, a contentcharged in a lower chamber will reach a inside compartment 25 a throughthe dip tube 28, and the communication hole 48 a of lower end of thehousing, and will go toward the stem hole 47 a. On the other hand, thecontent charged in the upper chamber goes directly to the stem hole 47 athrough the communication hole 48 b in a housing side attachment wall,and the channel 48 c. At this time, passage 48 c and compartment 25 aare in mutual communication, but a pressure gradient generated by apressurizing agent passes contents upwards, so this pressure does notallow communication holes 48 a and 48 b to flow backwards. Thereby, theupper and lower contents meet and mix in the stem 14. Here, each of thepassage 48 c and the compartment 25 a communicates substantially inindependent with the upper and lower chambers, respectively, and each ofthem demonstrates functions as a compartment holding each content (referto FIG. 7 a and FIG. 7 b). Thus, when the stem 14 of FIG. 3 b is used asa stem, each passage that communicates each chamber with the exterior ismutually independent and the contents charged in each chamber dischargefrom each chamber to exterior without mixing. Moreover, an example inwhich a dip tube is inserted in outside of a cylindrical part under thehousing is shown as a dip tube 28 here, but other insertion methodsbased on other Examples may be employed.

Next, as a discharging member used for an aerosol product of the presentinvention, conventional spouts and members with nozzle may be used, anddischarging members 29 a, 29 b, 29 c, and 29 e shown in FIG. 8 a, FIG. 8b, FIG. 8 c, and FIG. 8 g, and a discharging member 29 d shown in FIG. 9may also be used. Discharging members 29 a, 29 b, 29 c, and 29 e shownin FIG. 8 a through c and FIG. 8 g are preferably used with valves (forexample, a valve 13 b in FIG. 3 b, FIG. 5) that may discharge eachcontent independently, and discharging member 29 d in FIG. 9 may be usedwith valves enabling discharging of each content in a state mixedtogether therein (for example, a valve 13 a in FIG. 3 a, and FIG. 4; avalve 13 c in FIG. 3 c and of FIG. 6; a valve 13 d in FIG. 3 d), andwith valve enabling independent discharge of the contents.

A discharging member 29 a in FIG. 8 a has a cylindrical form having apartition wall provided in a center, and may provide a content passedthrough therein with a discharged content 30 a having a stripe-shapedcross section (refer to FIG. 8 d). Besides, a discharging member 29 b inFIG. 8 b has a cylindrical form concentrically divided into two layers,and, may provide a content passed through therein with a dischargedcontent 30 b having a two-layered cross section (refer to FIG. 8 e).Furthermore, a discharging member 29 c in FIG. 8 c has a cylindricalform having a divided circumference, and may provide a content passedthrough therein with a discharged content 30 c having a cross section ofspotted pattern (refer to FIG. 8 f). Besides, the discharging port 47may have a form extending tapered in a spatula-shape like a dischargingmember 29 e of FIG. 8 g.

A discharging member 29 d in FIG. 9 with form of a comb comprises; asupporting member 42 a engaging with a bead part of the valve; a beammember 42 continuously provided in the supporting member top; aplurality of branch member (teeth of a comb) 43 a vertically provided atequal intervals from the beam member side face; a stem engaging member42 c provided in a bottom face of the beam member 42; an opening 54 forchannel cleaning provided in a lower part of the beam member. The beammember 42 has a channel 42 b provided inside in a straight line from astem engaging member 42 c up to a top; a plurality of dischargingorifices 43 located on a side wall at equal intervals; and a pluralityof channels 42 d for connecting the channel 42 b and the eachdischarging orifice 43. Besides, branch parts 43 a are arranged at equalintervals between the discharging orifices 43 in the beam member sidewall. Thereby, the contents flow from the stem to the channel 42 bthrough the stem engaging member 42 c, and is discharged from eachdischarging orifice 43. Members of this form may effectively be used forcontents, such as hair dyes, treatment agents, and styling agents. Sinceaerosol products using this discharging member 29 d has the dischargingorifices 43 at the root of the branch part, combing action carriescontents for hair to hair automatically, enabling homogeneousapplication. Also, an opening 54 for channel cleaning is incommunication with the channel 42 b, and a conventionally well-knownball type check valve 54 a is provided near the opening. Furthermore, acleaning method shown in utility model No. 2567137 may be used. For thispurpose, a structure is adopted where contents do not leak from thechannel opening 54 to outside of the discharging member 29 d at the timeof use. Since such a cleaning method is provided, contents remaining inthe channel of the discharging members 29 d may be flushed off bypouring in water and washing liquid from the channel opening 54 afteruse. As discharging members for an aerosol product of the presentinvention, application device currently disclosed in FIG. 1 and FIG. 7of Japanese Unexamined Patent Publication No.10-236539 may be used.

In an aerosol container 10 of FIG. 2 constituted as mentioned above: afirst content A is charged in the lower chamber 26 from an top endopening of the inner bag 12; subsequently, the inner bag 12 iscompressed downward to close the center section 21 and to mutuallyisolate the lower chamber 26 and the upper chamber 27; then a secondcontent B is charged in the upper chamber 27 from the top end opening;then a propellant or a pressurizing agent are charged between the innerbag 12 and the container 11 using a method, such as under-cup charging;and the mounting cup 45 of the valve 13 is crimped to the container 11,to obtain a double-structured aerosol product (dispenser product).Actually, a stem 47 is further equipped with a push button or a spoutand a discharging member such as a discharging member 29 a in FIG. 8 a,a discharging member 29 b in FIG. 8 b, a discharging member 29 c in FIG.8 c, or a discharging member 29 c in FIG. 9, and furthermore awell-known discharging members. A jacket is given to the container withdischarging member to obtain a finished product.

In the above-mentioned manufacturing process, a flange 24 of the innerbag 12 is pushed downward in an axial direction of the container duringcharging of contents, after charging of a first content A to the lowerchamber 26. Thereby the inner bag is vertically shrunk to close thecenter section 21, As a result, the second content B will not easily bemixed with the first content A at the time of charging content B. Forthat purpose, this container enables charging of the second content B ata high speed, leading to an increase in working efficiency. Also, whenthe second content B is charged, the dip tube 28 is not yet attached,but the dip tube 28 is made to pass through a center of the centersection 21 after charging of the second content B. However, the centersection 21 may be closed after insertion of the dip tube 28 into theinner bag 12 and subsequently the second content B may be charged. Inthat case, only the dip tube 28 may be inserted first after charging ofthe first content A, and, subsequently the housing 46 may be fitted to atop end of the dip tube 28, after charging of the second content B. Orotherwise, the housing 46 and the mounting cup 45 may be attached in atop end of the dip tube 28 first, and, whole of the valve 13 may bedealt with as a module. Moreover, if a strength of the center section 21is set so that a charging pressure at the time of charging of the secondcontent B to the upper chamber 27 and a self-weight of the secondcontent B to be charged may shrink the center section 21 of the innerbag 12 and may separate the upper and lower chambers 26 and 27 from eachother. This makes easy charging of contents, propellants, orpressurizing agents, and easy crimping of the valve 13. Furthermore, inorder to eliminate oxygen remained in the container, a vacuuming of thegas or exchanging of an inert gases or a liquefied gas may be performedbefore charging of pressurizing agents. As a result, it enablespreservation of the contents over a long period of time as an aerosolproduct.

As contents charged in the inner bags used for an aerosol product of thepresent invention, both of the contents may be of a same kind, andpreferably may also be contents of different kinds from each other. Theabove-mentioned contents of different kinds from each other include: acase where states of the contents (concentration) that are to be chargedinto each of the chamber, that is, active ingredients; amounts ofblending, and blending components, such as solvent; and shape(difference of viscosity included) of contents, such as a shape ofliquid, gel, and cream, are different from each other; and furthermore acase where states of the contents, that is, homogeneous system, anduneven system; emulsion system, and dispersion system, (appearance ofcontents, such as color tone and transparent feeling) are different fromeach other.

In a dispenser product of the present invention, the contents arecharged in a container equipped with a plurality of the above-mentionedchambers mutually divided, both of the contents do not contact or mixwith each other in the state where the contents are being charged in thechambers. Accordingly, as contents to be charged in each chamber, theremay be used contents that cause reaction during or after discharging dueto the contact or mixing etc. of each chamber, or contents blended withreaction components that are activated by mixing. Also, the reactioncomponents may easily react with each other during or after dischargingsince contents easily mutually dissolve or mix are used. Thisdemonstrates the effects well. As reactions generated by contacting ormixing of the contents, neutralization reactions, hydration reactions,oxidation/reduction reactions, ion exchange reactions, dissolution,acidolysis, etc. may be mentioned. As effects obtained by the reactions,generation of heat, cooling, thickening, coloring (discoloration), filmformation, foaming, hidroschesis, etc. may be mentioned.

As combinations of reaction components participating in neutralizationreaction, there may be mentioned: water-soluble polymers and pHregulators (acid components or alkaline components); for example,carboxy vinyl polymers and alkali components, acrylic acid/stearethcopolymers, acrylic acid/ceteth copolymers and alkali components,acrylic acid/amino acrylic acids/PEG-alkyl (carbon numbers 10-20)copolymers, and acid components. These reagents may be used forapplication of setting agents for hairs, hair dyes, reduction ofinflammation painkiller, ant-heat flushes, coolants, etc., and theydisplay effects to thicken discharged contents (ejected matter) toimprove adhesion, or to improve durability of cool feeling.

As combination of reaction components participating in hydrationreaction, for example, there may be mentioned: polyhydric alcohols, suchas glycerin, diethylene glycols, and propylene glycols, and water; andinorganic powders, such as anhydrous silicic acids, zeolites, sodiumcarbonate, and potassium carbonate, and water.

These are used for applications, such as moisturizers, cleansing creamagents, pack agents, and shaving foams, and obtaining a sense of heatcaused by heat of hydration.

As combinations of reaction components participating inoxidation/reduction reaction, for example, dyestuffs, such asparaphenylene diamine, and oxidising agents, such as hydrogen peroxideand oxidizing enzymes; sodium sulfite and hydrogen peroxide; sodiumthiosulfate and hydrogen peroxide, etc. may be mentioned. These are usedfor applications, such as hair dyes, moisturing creams, cleansing creamagents, pack agents, and shaving foams, and obtaining effects, such ashair dyeing by coloring (discoloration), and blood circulationacceleration, skin maceration by generation of heat.

As combinations of reaction components participating in ion exchangereactions, sodium alginate and calcium lactate, etc. may be mentioned.These are used for application of formation of protective layers, foods,play goods, idea articles, etc., etc., and obtaining a film formationeffect.

As combinations of reaction component relating to dissolution, urea andwater, calcium chloride (anhydrous) and water, chloro hydroxy aluminumand water, etc. may be mentioned. A combination of urea and water isused for application of anti-itch agents, emollients, keratin clearanceagents, ointments, etc., and a feeling effect of cooling by endoergicreaction may be obtained. A combination of calcium chloride (anhydrous)and water is used for applications, such as moisturizers, cleansingcream agents, pack agents, shaving foams, and treatment agents, and heatsensation may be obtained.

A combination of chloro hydroxy aluminum and water is used asantiperspirants, and chloro hydroxy aluminum dissolves in water, and isionized to demonstrate hidroscheisis effect.

As combinations of reaction components participating in decompositionreactions, for example, carbonates, such as sodium hydrogencarbonate,sodium carbonate, potassium hydrogencarbonate, and potassium carbonate,and acids, such as citric acid, tartaric acid, and phosphoric acid, maybe mentioned. These component will decomposed to form carbon dioxide gasand when carbonates dissolve in aqueous solution including acid, andblending foaming agents, such as surface active agents together may givefoaming effect. These are preferable in hair care products, cosmeticsfor human bodies, unregulated drugs, medicines, etc., but theapplication is, however, not especially limited. Carbon dioxide gasgenerated may provide blood circulation facilitatory effect, and thismay be suitably used as hair restorers.

The reaction components are blended with different contents so that thereaction components may not react with each other in the state wherecontents are charged in a chamber. As examples of contents, for example,there may be mentioned compositions, such as: hair dyes described inJapanese Unexamined Patent Publication No. 10-45547, Japanese UnexaminedPatent Publication No. 10-287534, Japanese Unexamined Patent PublicationNo. 2001-2537, Japanese Unexamined Patent Publication No. 2001-288055,Japanese Unexamined Patent Publication No. 2001-294519, JapaneseUnexamined Patent Publication No. 2001-181159, Japanese UnexaminedPatent Publication No. 2002-367294; enzyme hair dyes described inJapanese Unexamined Patent Publication No. 63-46313, Japanese UnexaminedPatent Publication No. 06-172145; cleansing creams described in JapaneseUnexamined Patent Publication No. 07-173033 etc.; pack agents describedin Japanese Unexamined Patent Publication No. 06-336413, JapaneseUnexamined Patent Publication No. 08-268828, Japanese Unexamined PatentPublication No. 200119606; treatment agents described in JapaneseUnexamined Patent Publication No. 11-228332, Japanese Unexamined PatentPublication No. 11-279031; compositions for shaving described inJapanese Patent Publication No. 45-19996 official report etc.; and heatbuild-up compositions described in Japanese Unexamined PatentPublication No. 2003-19481, Japanese Unexamined Patent Publication No.10-306276.

As shapes of the contents, a shape of liquid, gel, cream, paste, etc.may be mentioned and the shapes are not limited in particular. However,it is preferable to use contents having viscosity, such as a shape ofgel, cream, paste, etc. giving little movement of reaction componentscaused by fluidity of the contents. In order to prevent unnecessaryreactions caused by contact of contents in housing inside the valves,between chambers of inner bags (partition wall part), and in adischarging channel etc., and also in order to reduce decrease of effectof the reaction components. A viscosity of contents is preferably noless than 100 cp, and more preferably no less than 1000 cp. An effectcontrolling movement of reaction components caused by fluidity may notbe obtained by a viscosity of less than 100 cp.

As states of contents, there may be mentioned: homogeneous system whereactive ingredients etc. are dissolved in a solvent; heterogeneous systemwhere oily components and aqueous components are separated; oil in watertype or water in oil type emulsion system where oily components andaqueous components are emulsified; and dispersal system where solidcontents, such as powders, are dispersed in solvents. These states arenot especially limited. The contents with few specific gravitydifferences and contents (solvent) that are mutually dissolved or mixedeasily are preferable, in order for reaction components in each contentto react easily after or during discharging and to easily obtaindemonstrated effects.

A charging percentage of the contents is preferably 5:1 through 1:5, andmore preferably 4:1 through 1:4 in a capacity ratio, in order tofacilitate adjustment of discharged amount of each contents, and inorder for reaction components to react easily, and further to easilydemonstrate the effects.

In a double-structured aerosol product in FIG. 2 constituted asmentioned above, the inner bag is always pressurized by pressurizingagents charged in a space between the inner bag 12 and the container 11,such as compressed gases, liquefied gases, and mixed gases of compressedgases and liquefied gases. Accordingly, internal pressure is generatedin the inner bag 12. As for the compressed gases, nitrogen gas, carbondioxide gas, nitrous suboxide gas, compressed air, and mixed gasesthereof, etc. may be mentioned. As the liquefied gases, LP gas, dimethylether and frons, and mixed gases thereof, etc. may be mentioned.Furthermore pressure regulation components, such as pentane, may be usedif needed. When the charging member is in operation in this state andthe valve 13 opens, a pressure in the housing 46 becomes almost same asexternal atmospheric pressure. When a valve (for example, FIG. 3 a) formixing within the housings 46 is used, a first content A enters into thehousing 46 from the lower chamber 26 of the inner bag 12 through the diptube 28. Simultaneously, a second content B similarly enters into thehousing 46 through the communication hole 48 from the upper chamber 27of the inner bag 12. And while both are mixed within the housing 46 orboth maintain a layer state, they are discharged outside from thedischarging orifice of the discharging member etc.

When the contents A and B are discharged, a pressure in the lowerchamber 26 is almost equal to a pressure in the upper chamber 27.Accordingly, a problem that only of one of the two contents manydischarged to leave another content remained, or a problem thatdifferent discharging amounts between each of the contents fail to makeactive ingredients react at a predetermined mixing ratio, and does notfully demonstrate a target effect, that is, problems caused by unequalpressurizing will hardly occur. Besides, in an embodiment shown in FIG.2, since the center section 21 of inner bag 12 is thinner than an uppertube (upper chamber), and furthermore the communication hole 48 is incommunication with an upper part of the upper chamber 27, the upperchamber 27 is crushed upward sequentially from the center section 21when remainder of the second content B in the upper chamber 27decreases. Similarly, since the center section 21 of the inner bag 12 isthinner than a lower tube (lower chamber), and the first content A inthe lower chamber 26 is sequentially discharged from an opening of alower end of the dip tube 28, the lower chamber 26 is crushed downwardsequentially from the center section 21. This lessens a possibility thatcontents A and B may remain in the inner bag 12. Further, as consumptionadvances, isolation of each content A and B further proceeds, andthereby a state where contents A and B are separated is still moreestablished, leading to excellent preservation of the both contents.

As examples particularly desirable as combinations of the contentscharged in the container of the above-mentioned present invention, twoliquid reaction type hair dyes and two liquid reaction type exoergicformulation may be mentioned.

Two liquid reaction type hair dye comprises a first agent includingoxidation dyes, and a second agent including oxidizing agents.

As the above-mentioned first agent, there may be mentioned agentsblended with solvents (purified water, lower alcohols, such as ethanol,alcoholic aqueous solution, etc.) including: oxidation dyes, that areoxidized with oxidising agents included in the second agent mentionedlater to give coloring, and that dye hair into desired color tones (forexample, paraphenylene diamine, N,N-dimethyl paraphenylene diamine,para-amino phenol, etc.), and alkaline agents (for example, ammonia,alkanol amines, etc.) in order to adjust pH of the first agent to arange of 6 through 12 and to stabilize the oxidation dyes and to improvehair dyeing effect.

Besides, in the first agent, in order to adjust colors of hair aftertreated, there may be blended: acid dyes (for example, Amaranthus,tartrazine, fast green, brilliant blue FCF, orange II, resorcin brown,alizurol purple, naphthol blue black, etc.); direct dyes (for example,4-nitro-o-phenylenediamine, 2-amino-4-nitrophenol, etc.); otherauxiliary components (for example, resorcin, paramethyl aminophenol,tannic acid, benzyl alcohol, N-methylpyrrolidone, etc.)

As the second agents, there may be mentioned agents blended withsolvents (purified water, ethanol, alcoholic aqueous solution, etc.)including: oxidising agents for oxidizing oxidation dyes anddemonstrating effect (for example, hydrogen peroxide and oxidizingenzyme (for example, laccase, peroxytase, uritaze, catalase, tyrosinase,etc.)); stabilizers (for example, EDTA, tannic acid, parabens, etc.); pHregulators (for example, phosphoric acids, citric acid, lactic acid,tartaric acid, etc.) etc.

Moreover, to both of the first agent and second agent, in addition tothe above-mentioned components: active ingredients (for example,treatment agents, moisturizers, UV absorbents, amino acids, vitamins,extracts, preservatives, perfumes, etc.) may be blended in order todemonstrate effects other than the hair dyeing effects; and there may beblended surface active agents (for example, non-ion based surface activeagents, silicone based surface active agents, etc.); viscosity controlagents (for example, cellulose type thickeners, carboxy vinyl polymesr,xanthan gums, etc.); oily components (for example, silicone oils, esteroils, hydrocarbons, fats and oils, higher alcohols, fatty acids, wases,etc.); and foaming agents (for example, LP gas, isopentane, etc.) etc.in response to discharging shape or feeling of use.

Next, two liquid reaction type exoergic formulation comprises a firstagent including exothermic components, and a second agent includingwater.

As the above-mentioned first agent, oily formulations in whichexothermic components generating heat that dissolve in water or hydratewith water (for example, magnesium chloride, zeolite, etc.) aredispersed in oily bases (for example, hydrocarbon such as liquidparaffin and liquid oil such as ester oils and silicone oils) may beused.

Besides, surface active agents for dispersing exothermic components (forexample, non-ion based surface active agents etc.); foaming components(for example, carbonates, such as sodium hydrogencarbonate and sodiumcarbonate); and thickeners (for example, palmitic acid dextrin etc.)etc. may be blended in the first agent.

As the second agents, water formulation including water, such as water,cream (water in oil type emulsions), and aqueous gels, etc. may bementioned. In order to maintain the exothermic effect, agents havinghydrophilic surface active agents dispersed in the oily bases as asecond agent may be used. When carbonate is included as a foamingcomponent in the first agent, it is preferable that acids (for example,citric acid etc.) for decomposing the carbonate and generating carbondioxide gas may be blended.

Moreover, active ingredients (for example, treatment agents,moisturizers, UV absorbents, amino acids, vitamins, extracts,preservatives, detergents, perfumes, etc.) for demonstrating effectsother than the exothermic effect; and foaming agents (for example, LPgas, isopentane, etc.) etc. may be blended in both of the first agentand second agent with or without the above-mentioned component.

Aerosol containers 60 in FIG. 10 a and FIG. 10 b have small diameters ofa body (for example, 10-40 mm), and they may be used in the case whereminiaturization of product is required, or where a small net weight isrequired because consumption in a short period is necessary due to poorstability of the contents. In the container 11 of the aerosol container,a top end is extended upwards, and depressed groove 61 projecting inwardin a radial direction is formed in a partly lower part of the top end.In addition, a mounting cup 45 of a valve is divided into an attachingpart 63 holding a housing 46 and a cover 64 for attaching the attachingpart in a container 11. Attaching part 63 has a flange 65 engaging witha top end of the container 11 via a packing 62, and a lower endperiphery is engaged with an upper part of a projection formed in aninner surface side of the depressed groove 61. Moreover, the cover 64has a cylindrical form with a bottom, and a vicinity of a perimeter ofthe lower end is crimped to the depressed groove 61. That is, the curvedflange 50 of the mounting cup 45 of the valve 13 is crimped to the bead17 provided in a top end of the container 11 in FIG. 2, but in case ofthe aerosol container 60 in FIG. 10 a, it is crimped to the depressedgroove 61, and they are different from each other in this point.Moreover, a top end of an inner bag 12 cylindrically extends upward sothat it may intervene between the top end of the container 11, and anattaching part 63.

In addition, an annular groove 65 a engaging with a projection on aninner surface of the depressed groove 61 of the container 11 is formednear the top end of an inner bag 12. Furthermore, clear pleat lines asin FIG. 2 a is not provided in a center section 21 of the inner bag 12,but triangle-shaped crevices are arranged so that they may become astarting point of folding in a part of a downward truncated cone 66 aand an upward truncated cone 66 b. Neither folding lines nor cornice areprovided in a cylindrical part 66 c between both of the truncated cones66 a and 66 b. However, when the inner bag 12 is vertically compressed,buckling will arise in the cylindrical part 66 c, and the inner bag 12will be folded, and closed, if only a starting point of folding isprovided. Other parts, for example, a shape of whole portion includingthe center section 21 of the inner bag 12, and materials and a shape ofthe container 11 are substantially same as in the double-structuredaerosol container 10 in FIG. 2.

Also in the double-structured aerosol container 60, in a same manner asin FIG. 2, after a first content A is charged into a lower chamber 26 ofthe inner bag 12, a top end an opening of the inner bag 12 is pressed toclose the center section 21, a second content B is charged into an upperchamber 27, then compressed gas etc. is charged between the inner bag 12and the container 11, and subsequently a valve is fixed, resulting in adouble-structured aerosol product of inner bag type (refer to FIG. 10b). And those charging process is easily performed. Thedouble-structured aerosol product thus obtained may be used almost in asame way as the double-structured aerosol product using the aerosolcontainer of FIG. 2, and they may discharge the first content A andsecond content B in a state mixed together or in a layered state.

In an aerosol container 67 shown in FIG. 11, two openable and closablecenter sections 21 are provided in the inner bag 12, and thereby, threeof upper, middle, and lower chambers 68 a, 68 b, and 98 c are obtained.And a through-hole 69 in communication with a middle chamber 68 b isformed in a middle part of a dip tube 28. In addition, the through-hole69 is preferably formed in the middle of the upper and lower directionof the middle chamber 68 b. Other parts are substantially same as inaerosol products in FIG. 10 b.

In the container, when a valve 13 is operated, a first content Ain thelower chamber 68 c enters into a dip tube 28 from a lower end of the diptube 28, a second contents B in a middle chamber 68 b enters into thedip tube 28 from the through-hole 69, then both of the first and secondcontents proceed together, and enter in a housing 46, and a thirdcontent C in a upper chamber 68 a enters in the housing 46 through thecommunication hole 48 in the housing 46. Thereby, three kinds ofcontents A, B, and C are discharged out in a mixed state, or in alayered state. The container is substantially same as the aerosolcontainer 60 of FIG. 10 b in other points, and substantially sameoperational advantage may be demonstrated. In addition, there may beprovided two dip tubes, that is, a dip tube 28 communicating the lowerchamber 68 c with the housing 46, and a short dip tube communicating themiddle chamber 68 b with the housing 46. In that case, two kinds ofcontents B and C will not mixed together within the dip tube.

In an aerosol container 70 in FIG. 12 a, upper and lower chambers in aninner bag 12 has a different volume from each other, the upper chamber27 has a larger volume than the lower chamber 26, and a volume ratio isabout 4:1. Volumes of each chamber may be arbitrarily set based onvolumes of contents to be charged, and on a ratio of desirabledischarging amount. However, a volume ratio of upper and lower chambersis preferably 5:1 through 1:5 in consideration of ease of adjustment ofa discharging amount ratio based on a length and a hole size of thechannel or the passage. Moreover, in a middle part of the inner bag 12,a constriction part 71 smaller than a opening of the container 11 isprovided. And a partitioning member 72 closely engaged with theconstriction part 71 from upper side is attached in a perimeter of thedip tube 28. Thereby, the constriction part 71 may be closed by thepartitioning member 72 without opening and closing action of theconstriction part 71 itself. In this configuration, if the dip tube 28is inserted and the constriction part 71 is closed by the partitioningmember 72 after charging of the first contents A to the lower chamber 26of the inner bag 12, the lower chamber 26 and the upper chamber 27 willbe isolated. Subsequently, if the second content B is charged in theupper chamber 27, the first content A and the second content B will notbe mixed. Therefore, this configuration also enables high-speed chargingof the second content B, and provides a high working efficiency. In thisembodiment, although the constriction part is narrowed in a taperedshape, it may have a valleys-and-peaks shape. A tapered shape, however,may realize easier insertion of the partitioning member. Moreover, inthis aerosol container 70, the constriction part may be thicker thanother parts of the inner bags, which further strengthens engagingbetween the partitioning member and the constriction part, and does noteasily cause omission. Furthermore, preferably, vertical grooves (notshown) are preferably provided in a periphery surface of a chamber ofthe inner bag so that the inner bag may easily shrink, which mayefficiently shrink the inner bag and may reduce a residual quantity ofthe contents after use.

In addition, a configuration may also be employable that thepartitioning member 72 is constituted by elastic members, such as spongeand rubber materials, a through-hole 73 for letting the dip tube 28 passis formed in a center portion being openable and closable, and isolationis always realized by elasticity of the elastic members. In that case,after charging of the first content A, only the partitioning member 72is put into the inner bag 12, and then the constriction part 71 isclosed, subsequently, the dip tube 28 is put into the inner bag 12,after charging of the second content B into the upper chamber 27, andthen may be inserted into the through-hole 73 of the partitioning member72. And in this case, since the valve 13 equipped with the dip tube 28may be crimped to the container 11 after the charging of the contents,almost same operations as usual may be done, and a high workingefficiency may be realized. Moreover, the constriction part 71 is setsmaller than an opening of the container 11 in order to make insertionof the partitioning member 72 from the opening easier, and a size of theconstriction part 71 is not particularly limited, when the partitioningmember 72 is constituted with flexible materials, such as sponge.Further, an O-ring may be provided inside of the constriction part, oroutside of the partitioning member. This will increase sealing statebetween the upper and lower chambers, and preferably further preventsmixing of the contents in the upper and lower chambers within the innerbag. In addition, some elastomer may be arranged from exterior towardinside of the constriction part. Furthermore, a step or a leveldifference may also be arranged at the constriction part and thepartitioning member. Thereby, the constriction part and the partitioningmember are clipped and fitted in. Also in this case, sealing statebetween the upper and lower chamber increases, and a same function as inthe above-mentioned embodiment may be demonstrated. Especially, when athickness of constriction part is increased, separation of the clipfitting is hard to occur, which is preferable.

An aerosol container 75 in FIG. 12 b, upper and lower chambers of theinner bag have different volumes from in FIG. 12 a, and a lower chamberhas a larger volume than an upper chamber. Moreover, except for apartitioning member 72 being provided with a shape of a stopper bodythat fits in deeply in a constriction part 71, this container has a sameconfiguration as in the aerosol container 70 in FIG. 12 a. This has ahigh sealing property between a lower chamber 26 and an upper chamber27. In other points, same operational advantage will substantially bedemonstrated as in the aerosol container 70 in FIG. 12 a.

An aerosol container 75 a in FIG. 12 c has a dip tube 28 having a lengthreaching to a partitioning member 72, and an engaging member 74 formaking insertion of the dip tube 28 to a valve easier. The engagingmember 74 is attached to the housing, and it has a cylindrical form, anda lower opening where the dip tube is to be inserted has a formcurrently opened downward in a tapered shape. When a valve is put on thecontainer opening in manufacturing process of the aerosol product, thisguides a tip of the dip tube to a loading slot of the engaging member74, and ease the insertion of the dip tube to the valve. Also, thepartitioning member and the dip tube may be highly adhered with asealing material beforehand. As shown in an imaginary line shows, theengaging member 74 may be engaged with the inner bag, which maythoroughly isolate contents in the upper chamber from the valve. Thisconfiguration may be preferably used, when the contents in the upperchamber has a high corrosion behavior over the mounting cup.

Although in the aerosol container 70 in FIG. 12 a, the aerosol container75 in FIG. 12 b, and the aerosol container 75 a in FIG. 12 c, the diptube 28 is directly inserted in the partitioning member 72, thepartitioning member 72 and a lower end of the housing 46 of the valvemay be closely connected, by a tube 28 a having a larger thickness thanthe dip tube 28, as in an aerosol container of 12 d in FIG. 75 b, andthen the dip tube 28 may be inserted into it. In this case, whole of thepartitioning member 72 and the tube 28 a, or a tube 28 a itself having athick part whose lower end is fitted into the constriction part 71 makesa substantial partitioning member. Thus, use of the thick tube 28 aarranges the top end near an opening of the inner bag 12, and thus makesinsertion of the dip tube 28 easier. Moreover, the thick tube 28 a maybe extended to a vicinity of a bottom of the inner bag, as shown inimaginary line. A top end of the tube 28 a may be attached in peripheryof a lower end of a valve housing. In that case, in accordance with thecommunication hole 48 provided in a side wall of the housing 46, a cutis provided in the tube 28 a near a top end of the tube 28 a.

Besides, as shown in FIG. 12 f, a configuration may also be employablethat a thick part 71 b is provided in the dip tube 28 itself, the thickpart is inserted in the constriction part 71, and thereby upper andlower chambers are mutually isolated. In this case, the dip tube 28itself serves as a partitioning member. Also, in any case of FIG. 12 athrough FIG. 12 d, it is preferable that a lip-seal 71 a, as shown inFIG. 12 e, is prepared in the constriction part 71. A still moreadvanced sealing property may be realized between upper and lowerchambers in these cases. In addition, the lip-seal 71 a may be preparedin the partitioning member 72 side. In FIG. 12 c, same lip-seal 71 a maybe prepared in the tube 28 or in the engaging member 74, and therebysealing property between the engaging member 74 and the tube 28 may beimproved.

Additionally, partitioning members 72 b, and 72 c as shown in FIG. 13 aand FIG. 13 c may also be used. A partitioning member 72 b in FIG. 13 acomprises a cylindrical body 150; a flange part 151 currently formed inan upper part of the body in a tapered shape; and legs 152 that arecylindrically located in a line on a lower side face of the body at apredetermined spacing, and that has hook parts 153 projecting outside ina radial direction at the end. The legs 152 are located in a linecylindrically, so it has elasticity in a radial direction, and thereby,clip fitting of the leg 152 is realized to a lower part of theconstriction part of the inner bag. Therefore, the fixing of thepartitioning member 72 b is supported by the constriction part, legs152, and the flange part 151. That is, in a state of the dip tube isinserted, a lower chamber of the inner bag will be thoroughly sealedexcept for a channel of the dip tube when the partitioning member 72 bis made to fit in. As an inner bag to be engaged to such partitioningmember 72 b, a flange for enabling engaging with a hook part of thepartitioning member may be provided in a lower part of the constrictionpart of the inner bag (refer to FIG. 13 b). Furthermore in theembodiment, a body of the partitioning member 72 b has a cylindricalform, but it may have a form of tapered truncated cone being thinneddownward. In that case, an inner surface of the constriction part of theinner bag is also set so that it may have a tapered form having a sameinclination, which makes a small clearance between the constriction partand the partitioning member, and strengthens more sealing state betweenthe upper and lower chambers of the inner bag.

The partitioning member 72 c of FIG. 13 c comprises a cylindrical body160 having a bottom; a flange part 161 formed in an upper part of thebody in tapered shape; and a cylindrical engaging member 162 projectingfrom a top face of the body and fitting in freely slidable state with alower end of the dip tube. Further, a communication hole 163 incommunication with an inside of the engaging member 162 is provided in acenter of a top face of the body. The body has an O-ring 164 in a centerof a periphery surface, and an inner surface is closed in a taperedshape toward the communication hole 163. This O-ring 164 seals an areabetween the constriction part of the inner bag, and the partitioningmember 72 c. Thus, the partitioning member 72C is fixed in an upperdirection with the O-ring 164, and is fixed in a downward direction withthe O-ring 164 and a flange part 161. Moreover, since an inner surfaceof the partitioning member is closed in a tapered shape, a flow of thecontents becomes smooth and clogging caused by them may be prevented.Although the O-ring is used as a seal between the constriction part andthe partitioning member in the embodiment, a projection projectedoutside on a side face of a periphery of the partitioning member in aradial direction and/or a projection projected inward on an innersurface of the constriction part of the inner bag in a radial directionmay be provided. Furthermore, a metal ring may be provided to crimp fromoutside of the constriction part of the inner bag.

The engaging member 162 fixes a lower end of the dip tube 28, and has anO-ring 165 inside, and this provides sealing while allowing movement inan axial direction between the dip tube and the partitioning member. Thedip tube used for this partitioning member 72 c has a length from avalve to the partitioning member. Furthermore, in this engaging member,the dip tube is equipped with a clearance between a tip of the dip tubeand a top face of a body of the partitioning member, so that dip tubewill be able to move vertically. Accordingly, the dip tube may not bedisconnected even if a force applied to the inner bag deforms the innerbag when contents are charged into the inner bag using this partitioningmember 72 c, and even if an impact is applied to the container whendropped during the transportation or in use in which the inner baghaving flexibility expands and contracts up and down. Further, the diptube is supported and the dropping of the dip tube to the lower chamberwill be prevented even when engagement between the dip tube and thevalve is weakened, such as in the case where the dip tube isdeteriorated by the contents to result in expansion. Furthermore, gasaccumulated between the partitioning member and the lower chamber at thetime of charging of the contents may be removed by opening the valve.

Moreover, the engaging member 162 may be projected high from the body160 in a shape of a chimney, like the partitioning member 72 d shown inFIG. 13 d. In this engaging member 162 (inside the chimney), the diptube 28 is freely slidable. The dip tube 28 may be engaged to theengaging member 162, so the position of the valve attached to the top ofthe dip tube will be set in the position higher than a opening of thecontainer. This will allow easier charging of the contents.

Furthermore, a tip of this engaging member 162 may be directly contactedto a lower part of the valve housing. Thereby, when the valve is fixed,the valve presses the partitioning member 72 d via the engaging member162, which will prevent omission of the partitioning member 72 d fromthe constriction part. In addition, as shown in imaginary line, sameeffect as in a case of an aerosol container having an engaging member 74may be obtained. Also, a tip of an engaging member 162 may be directlyinserted into an engaging member 74 without use of a dip tube.

Here, FIG. 33 shows a method for manufacturing an aerosol product 190 bhaving a partitioning member 72 e whose engaging member 162 is projectedhigh from a body 160 like a partitioning member of FIG. 13 d. First, acontent A is charged into a lower chamber from an opening of an innerbag 12 inserted in a container 11 (FIG. 33 a). At this time, an innerbag 12 beforehand charged with a content A may be inserted into acontainer 11. Subsequently, a partitioning member 72 e equipped with adip tube is inserted in a constriction part 71 of the inner bag, andthen a content B is charged into an upper chamber 27 (FIG. 33 b). Here,a lower end (an engaging member 74) of a valve 13 is contacted to a tipof the dip tube 28, the valve 13 is placed, while pushing down the diptube 28 until a state is realized where under cup charging of apressurizing agent is enabled (FIG. 33 c). Furthermore, air in a space56 between the container 11 and the inner bag 12 is removed byvacuumizing, or gas flushing, etc. Thus, removing of residual air in thespace 56 prevent reaction between the contents and residual air, andimprove stability of the contents. Subsequently, a pressurizing agent ischarged into the space 56 and the valve 13 is fixed. In addition, when abottom of the container has a gas charging valve 121 as shown in FIG.24, a pressurizing agent may be charged after fixation of the valve.Finally, a stem 14 is pushed down, the valve 13 is opened wide, and agas 57 mixed in the upper and lower chambers 27 and 26 at the time ofcharging of the contents is removed (FIG. 33 c, d). Thus manufacturedaerosol product 190 b will prevent activated discharge of the contentsaccompanied by mixing with gas at the time of beginning of use.Moreover, this may control a residual oxygen concentration in theaerosol product no more than 1%, and preferably no more than 0.1%. Thisprevents reactions of the container and the oxygen, even if the contentshave reactivity with the oxygen, realizing stable preservation over along period of time.

In addition, FIG. 34 shows other method for manufacturing an aerosolproduct 190 c having of partitioning member 72 f. In the aerosol product190 c, there is provided a configuration that enables discharging,avoiding for contents in upper and lower chambers mixed together withina valve 13 like the valve 13 b shown in FIG. 5. Here, description willbe given using a valve 13 b in FIG. 5. In a method for manufacturing theaerosol product 190 c, a valve 13 b is placed without charging ofcontents, air in a space 56 between a container 11 and an inner bag 12is removed, a pressurizing agent is charged into a space 56, and thenthe valve 13 b is fixed (FIG. 34 a). Here, a stem 14 is pushed down, thevalve 13 is opened, and air in the upper and lower chambers 27 and 26 isremoved (FIG. 34 b). Subsequently, a content A is charged into the lowerchamber 26 from one passage 18 a of the valve 13 b with the otherpassage 18 b of the valve 13 b closed (FIG. 34 c). Next, a content B ischarged into the upper chamber 27 through the passage 18 b of the valve13 b with the passage 18 a of the valve closed (FIG. 34 d). An order ofthe charging of these contents A and B may be reversed. Such a methodfor manufacturing an aerosol product 190 c is preferable, because thecontents A and B can be charged without contacting with air. Inaddition, as described in FIG. 33, when a bottom of the container has acharging valve 121, charging of a pressurizing agent may be performedafter fixation of a valve, or may be performed after charging of thecontents to each chamber. Moreover, when a valve of a structure having aspace between a mounting cup, and a periphery surface of a housing isused, a clearance is formed between a stem rubber and a mounting cupwith bending of a stem rubber caused by a pressure power, and thencontents may be charged into an upper chamber from a periphery of a stemthrough the clearance.

FIG. 35 shows an aerosol product 190 d in which a partitioning member 72f and a valve 13 are connected by a tube 28 c having flexibility. Thetube 28 c having flexibility here has a sufficient length after thevalve 13 is fixed, it may bend within an upper chamber 27 like shown inFIG. 35. In the aerosol product 190 d, a constriction part 71 of aninner bag may be equipped with the partitioning member 72 f (FIG. 35 a)in a state where a top end of the tube 28 c and valve 13, and a lowerend of the tube 28 c and the partitioning member 72 f are attached,respectively. That is, since a lower end of the valve does not need tobe contacted nor engaged to a tip of a dip tube during the placement ofthe valve, which will make the installation of the valve easier.Furthermore, when contents are charged into an upper chamber, As shownin FIG. 35 a, the tube is bent and the valve is shifted from an openingof the inner bag, so that the charging of contents becomes easier.

An aerosol container shown in FIG. 14 b, comprises a container 11 a; aninner bag 12 that has a constriction part 71 in a body and an expandablecornice 194 provided in a neck part; a partitioning member 72 that hasan engaging member 162 equipped with a constriction part 71 of the innerbag, that isolates a lower chamber 26 and an upper chamber 27, and thathas a tapered inner surface of a top end; and a discharging member 190 aequipped with a valve. The aerosol container 190 further comprises anengaging member 74 allowing easier insertion of a dip tube 28 into thelower part of the housing of the valve 13, and other configurations aresubstantially same as in the aerosol product 75 a shown in FIG. 12 c.

A container 11 a has a same top end as in the container 11 of FIG. 10 ain which extends upwards and a depressed groove is formed at in somedown side to the top end in a radial direction. The container 11 a islong and slender.

The partitioning member 72 has a through-hole 73 so that the dip tube 28may be inserted to penetrate through the partitioning member. A lowerend of the dip tube 28 passes through the through-hole 73, and islocated in the lower chamber 26 after the charging (FIG. 14 b).

The engaging member 74 comprises cylinder part 197 that closely attachedto the periphery of the dip tube engaging part of the lower part of thehousing; and tapered part 198 that expands downwardly from the bottomend of the cylinder part to the bottom, and the inner surface of thetapered part forms insertion part 193 having praboloid of revolution.Therefore, the tip of the dip tube equipped beforehand to thepartitioning member abuts with the inserting part 193 of the engagingmember 74, just only by placing the valve to the opening of thecontainer at the processing of the aerosol product. As a result, theprocess to attach the dip tube to the valve 13 will be eased.

The discharging member 190 a has a means to mix the contents dischargedfrom the valve and the inside channel or passage of the dischargingmember has a configuration of helix mixer. Thus, the contents mixed inthe valve will be mixed equally within. As for the discharging member adischarging member shown in the Japanese Unexamined Utility ModelPublication No. 64-25357 and Japanese Unexamined Utility ModelPublication No. 04-100483 may be used.

A method for manufacturing the aerosol product 190 a, a content A ischarged into the lower chamber 26 from the opening of the inner bag 12inserted into the container 11 a. Next, the partitioning member 72equipped with the dip tube 28 is inserted into the constriction part 71,and a content B is charged into the upper chamber 27. Further, the valve13 equipped with engaging member 74 is attached to the dip tube 28, acompression air or the kind is charged into the space between thecontainer and the inner bag by method of under-cup charging (FIG. 14),and a cover of the valve is crimped with the inner bag 12 being pushedinside the container and fixed to the depressed groove of the container.When the valve is fixed, the location of the top of the inner bag lowerscompare to the time of charging contents (FIG. 14 b). The aerosolproduct is easily manufactured because the inner bag has the cornicepart that enables the expansion and contraction of the inner bag 12 inaxial direction. In addition, the contents can be charged safely intothe upper chamber without inserting into the dip tube, when thepartitioning member that can be penetrated by dip tube is used. Itenables the top of the dip tube to set higher than the opening of theinner bag.

The aerosol container product 180 shown in FIG. 15 is provided with adip tube 28 c, and other configuration are substantially same as theaerosol container 1.

The dip tube 28 c is composed of two tubes 28 a, 28 b having differentdiameter and the thin diameter tube is inserted into in the largediameter tube. The inner diameter of the thick tube 28 a is made to bepractically same as the outer diameter of the thin tube 28 b, and thethin tube 28 b is longer than the thick tube 28 a where the length ofthe thick tube 28 a is same as the distance between the dip tubeengaging part 55 and the engaging part 162 of the partitioning member 72in the condition that the valve 13 is crimped.

The manufacturing method of the aerosol product 180, first the content Ais charged in the lower chamber, the partitioning member72 equipped withthe dip tube 28 is inserted into the constriction part of the inner bag,and the thick dip tube 28 a is extended so that the upper end protrudeshigher than the opening of the inner bag (FIG. 16). The content B ischarged, the valve is mounted, the dip tube 28 c is retracted so thatthe thin tube 28 b protrudes from the upper end, and the dip tubeengaging part 55 and the dip tube 28 c (practically the thin dip tube 28b) is engaged (FIG. 15). After that, a propellant is charged and themounting cup is crimped. In this condition, the each ends of the thintube 28 b mates with the dip tube engaging part 55 of the valve and theengaging part 162 of the partitioning member 74. The each ends of thethick tube 28 a mates with inside of the insertion 193 of thepartitioning member 74 and the upper end inner surface of the engagingpart 162 of the partitioning member 74. Thus the thin tube 28 bpractically serves as a dip tube of the aerosol product. The thick tube28 a serves as a guide in assembling and prevents the contact betweenthe content B in the upper chamber and the content Ain the thin tube 28b to make the content more stable.

In this embodiment, the case that the thin tube is longer than the thicktube is described, however the thick tube may be longer than the thintube. In this case, when the valve is crimped, the each ends of thethick tube engage with the dip tube engaging part 55 of the valve andthe engaging part 162 of the partitioning member, and the thick tubeserves practically as a dip tube of the aerosol product.

The inner bag 76 shown in FIG. 17 a has a center part 21 of cornice thatcan expand and contact in up and down direction. In other words, thefirst truncated cone 77 closing downward continues to the lower end ofthe cylindrical wall of the upper chamber 27, the second truncated cone78 expanding outward and facing downward continues to the lower end ofthe first truncated cone via the fold line of a valley fold. Further,the third truncated cone 79 closing downward continues to the lower endof the above cone via the fold line of a mountain fold. Similarly, atthe upper end of the cylindrical wall of the lower chamber 26, half ofthe cornice 80 b is formed which is turned half of the cornice 80 acomposed of the above first, second, and the third truncated cone 77,78, 79. Thereby forming one cornice 80 as a whole continuing the upperhalf cornice. The width of the first truncated cone 77 and the thirdtruncated cone 79 is preferable to be wider than that of the secondtruncated cone 78.

The inner bag 76 composed as above has a wide area of the opening whichis surrounded by the fold line 81 of valley fold that continues theupper and lower half of the cornice 80 a and 80 b. In other words, thefold line 81 that continues the third truncated cone 79 each other, inthe condition extended upward and downward as shown in FIG. 17 a. Whenthe inner bag is retracted up and down as shown in FIG. 17 b, the foldline 81 is pushed inside making the surrounded area of the openingsmall. Accordingly, the same action as the inner bag 12 in FIG. 2 isobtained. In addition, as shown in FIGS. 12 a and 12 b, the partitioningmember 72 can be simultaneously used. Further, the cornice 80 is notlimited to be circular and can be rectangular in cross section.

The inner bag 82 shown in FIG. 18 a is provided with a cylindricalconstriction part 71 at the center part 21, and at its center asemicircular thin or thick fold line 83 is formed. In this embodiment,the fold line 83 is discontinued at the two facing parts 84 of frontside and rear side. When this inner bag 82 is used, the middle of theconstriction part 71 is squashed left and right along the fold line 83after the first content A is charged in the lower chamber 26, as shownin FIG. 18 b. Thus, the communication between the upper and lowerchamber 27,26 is blocked off. In the squashing, the discontinued part 84of the fold line is less flexible, therefore the squashing begins atthis point and goes on along the fold line 83. Resultantly, as shown inFIG. 18 c, the discontinued part 84 expands in crosswise direction. Thissquashed condition can be maintained by applying a force in up and downdirection. The dip tube 28 can be inserted before the squashing ordirect after the squashing, or after that the content B is charged inthe upper chamber 27. In the latest case the dip tube can be inserted byunclenching.

It is possible not to provide the constriction part 71 and provide onlythe fold line 83. However in this case the discontinued part of the foldline 84 protrudes outward (see FIG. 18 c), causing the possibility tostrike the inner surface of the outer container 11. Therefore it ispreferable to provide the constriction part 71 to limit the projectionwithin a given range. Further, in both cases that constriction part 71is provided or not provided, the fold line 83 can be omitted. However,the provision of the fold line 83 brings smooth squashing and stablesthe condition after squashing.

In the case of FIG. 18 a, a cylindrical part is provided in themidstream of the constriction part 71, but as the center part shown inFIG. 10, the cross section viewed from front or side of the constrictionpart can be V-shaped. In this case, its shape after squashing isdistinct and stable. The constriction part 71 is usually provided withcircumferentially equal intervals, but they can be provided unequallysuch as decentered in one side. In this case, when an up and down forceis applied, a bending moment acts in the constriction parts and theinner bag is squashed naturally by buckling action. The cross section ofthe constriction part 71 viewed from the top can be made elliptical orrectangular with its dimension short in right and left in FIG. 18 a andlong in right and left in FIG. 18 b. In this case, it can be smoothlysquashed and this shape is stable after the squashing.

Further in FIG. 18 b, a concave groove can be provided on the one sidewall of the squashed portion and a convex brace engaging with theconcave groove can be formed on the other side to fit each other. In thecase of FIG. 18 a, the discontinued part 84 of the fold line 83 isprovided to make it a starting point of squashing. But for example, asthe inner bag 85 shown in FIG. 19 a and FIG. 19 b, it is possible tomake it a starting point by picking a part 86 of the outside wall and toputting together by heat sealing. It is also possible to fold in and toput together by heat sealing. In any case, because the part 86 (a partof the outside wall) put together becomes a lengthwise rib to determinethe direction of fold, it is smoothly folded. It is also possible toform an outward rib having arc cross-section or an inward rib. Further,as shown in FIG. 19 c, FIG. 19 d, a platy lengthwise rib 87 in theconstriction part of the inner bag 85 is integrally formed and puttogether after forming. In this case, in the middle point of thelengthwise rib, a hinge 88 for a starting point of folding can beformed.

In any of the above embodiment, after squashing the center part aftercharging the first content, the squashed portion can be tightly puttogether by heat sealing, ultrasonic welding, high frequency inductionwelding, adhering by adhesive leaving the through hole for passing thedip tube. Thus the sealing property between the chambers becomes high.In any of the embodiment described above, number of the chamber is notlimited to two and it can be three or more than four.

In the inner bag shown in FIG. 20 a, the upper and lower chamber isdivided into the upper chamber member 85 b and the lower chamber member85 a. The upper chamber member 85 b is tubular having the body 89 a; theshoulder part 89 b extending in tapered shape from the upper and lowerend of the body 89 a; and the neck part 89 c extending from those ends.Further a flange part 89 d is formed on the upper end of the upper neckpart and a female screw 98 a is formed on the inside of the lower neckpart. The lower chamber member 85 a is tubular with having the body 89a; the shoulder part 89 b extending in tapered shape from the upper endof the body; and a neck part 89 c whose diameter is smaller than thebody and extending upward from the upper part of the shoulder part, anda male screw 98 b is formed on the outside surface of the neck part. Thefemale screw 98 a of the under neck part of the upper chamber member 85b and the male screw 98 b of the neck part of the lower chamber member85 a can be connected and this screwing forms substantially one innerbag 85. Thus the connected point of the inner bag 85 corresponds to theconstriction part. When the inner bag 85 is used as a container of thisinvention, the above described partitioning member can be used as apartitioning, but it is possible to use a thin film (not shown) such asaluminum foil or synthetic resin as a sealing at the contact face of theupper and the lower chamber member or opening of the under shoulder partof the upper chamber member. And furthermore, the upper chamber member85 b can be formed of cylindrical shape with bottom. Then, the contentsare charged in the each chamber, and the upper and the lower chamber isconnected to each other. After inserted into the outer container, thefilm is ripped or broken by the dip tube 28 at the time when the valveis mounted on the outer container to obtain the container of thisinvention. As a connecting means, screws are used here, but it is notlimited to this. The diameter of the upper and lower openings can bemade different so as to fit in. Further, fitting in of tapered surfaceinto each other can be used. As such dip tube 28, the edge of the tubeis preferable to be sharp so that it can break the film etc. easily.Without use of films, sealing of the upper and the lower chamber can bedone using a dip tube 28 having practically the same outer diameter asthe inner diameter of the connecting part.

The inner bag 85 d, as shown in FIG. 20 b, is made of metal such asaluminum. The inner bag 85 a is composed of the upper and the lowerchamber member 85 a and 85 b like the inner bag 85 of FIG. 20 a. Theupper and lower chamber members are formed by gluing aluminum sheet orlaminated sheets of resin sheet and aluminum sheet together. The upperchamber member 85 a is formed by tucking a cylindrical upper neck part86 a and a cylindrical lower neck part 86 b with female screw with twoaluminum sheets, and by gluing the edges together. The lower chambermember 85 b is formed by tucking the cylindrical neck part 86 d havingmale screws with aluminum sheets, and by gluing together. The inner bag85 d is formed by screwing in the under neck part 86 b of the upperchamber member and the neck part 86 d of the lower chamber member 85 b.

As a charging method of the dispenser of this invention using this innerbag, the bottom is formed by affixing a thin film in the inside surfaceof the tapered under shoulder 89 b of the upper chamber member 85 b, thecontents are charged in the upper and lower chamber through separatelines, and these chamber members are connected to be inserted into theouter container. Next, the valve with a dip tube is fitted on the upperneck part of the upper chamber member to break the film, a propellant ischarged and the valve is fixed. Otherwise, the contents are charged intothe lower chamber member 85 a and the film is covered, the upper chambermember 85 b is connected, the content is charged in the upper chambermember, the charged inner bag is inserted into the outer container, andthe valve is inserted to charge the propellant. This method allowshigher production speed. Further, long term stable storage of thecontents may be achieved, because the material of the inner bag suitablefor the contents can be used.

In the case that the film is not used and the upper and the lowerchamber member are sealed by a dip tube having practically the sameouter diameter as the inner diameter of the connecting part, the contentis charged into the lower chamber member, the upper chamber member isconnected, the dip tube is inserted, the content is charged into theupper chamber member, and then the propellant is charged. In this case,the contents can be charged in the order of the lower chamber member andthe upper chamber member after the upper and the lower chamber memberare connected.

Further, the film and the dip tube having the same outer diameter as theinner diameter of the connecting part may be used to enhance the sealingeffect.

The inner bag of FIG. 21 has the constriction part 71 dividing the innerbag into the upper and the lower chamber in the vicinity of its center.The inner diameter of the upper chamber 27 is larger than the innerdiameter of the lower chamber 26 and the diameter of the opening of theouter container, and the inner diameter of the lower chamber 26 issmaller than the diameter of the opening of the outer container. Thecharging method of the container product using this inner bag 185, firstthe content A is charged into the lower chamber 26, the lower chamber 26of the inner bag 185 is inserted into the outer container 11 where theshoulder part 186 composed of the upper chamber 27 and the constrictionpart 71 is hooked on the opening of the outer container 11 shown by theimaginary line. Then, the partitioning 72 equipped with the dip tube isinserted into the constriction part 72, the inner bag 185 is vacuumizefrom the opening to deflate the upper chamber 27, and the inner bag 185is inserted into the outer container 11. After that, the content B andthe propellant is charged with conventional methods. This chargingmethod allows lower oxygen density in the inner bag and the long termstable storage of the contents, because the contents are less exposed tooxygen after charging. Thereby enabling long term stable storage of thedispenser (aerosol products).

In the inner bag 187 of FIG. 22, the constriction part 71 is formed inslender shape in the vicinity of the center, and divide the inner baginto the upper and the lower chamber 27, 26. The diameter of theconstriction part 71 is practically same as the outer diameter of thedip tube 28. The insertion of the dip tube 28 isolates the upper andlower chamber except for the path of the dip tube 28. The slenderconstriction part prevents the contact of the content A and the contentB, and adjustment of thinness and length of the constriction partsenables to obtain desired stability. The charging method of thiscontainer product using the inner bag 187 is described as follows. Atfirst, the content A is charged in the lower chamber 26, the dip tube 28is inserted into the constriction part 71, and the content B is chargedin the upper chamber 27. A lip can be provided with the constrictionpart 71 to secure the sealing property.

The aerosol container 90 of FIG. 23 is provided with an outer container91 made of transparent or translucent rigid synthetic resin orpressure-resistant glass, the inner bag 92 having the upper and thelower chamber 92 a, 92 b inserted into the container 91, and the valve93 fixed on the opening of the outer container.

The outer container 91 has a cylindrical body with bottom, the shoulderpart extending in tapered shape from the upper end of the body, and theneck part continuing from the shoulder part. Under the end of the aboveneck part, a concave groove 91 a is formed continuing from the upper endof the shoulder part. The outer container 91 is manufactured byconventional blow molding method, a parison made of polyethyleneterephthalate or synthetic resin of polyethylene terephthalate etc isinflated using air pressure, the inflated parison is closely contactedto a metal mold, and the hollow body is obtained by cooling down.Further the shape of the container disclosed in Japanese UnexaminedPatent Publication No. 2000-327053 may be used. By making the outercontainer transparent or translucent, it is possible to view the insidecontent to check the accurate remaining amount and the condition of theupper and lower chambers. Especially for the aerosol products filledwith the contents, which reacts when the contents of upper and the lowerchamber are mixed with each other. Further providing a scale on theouter container is preferable because it enables the accurate check ofthe remaining amount and the condition of the contents. In thisembodiment, the remaining amount of the content can be checked byexternal view because the outer container is transparent or translucent.In other cases where the outer container is not transparent, a thread ora string is preferable to be connected in the middle stream of up anddown direction of the product. In this case, it is possible to check theremaining amount of the contents by the inclination of the product whenanother end of the thread is tucked to hang the product.

The inner bag 92 described above is practically same as the inner bag187 of FIG. 22. It is provided with the constriction part 94 which issmaller than the opening of the outer container 91. The constrictionpart 94 divides the inner bag into the upper and the lower chamber byinserting the dip tube. However, in the periphery of the constrictionpart 94 between the upper chamber 92 a and the lower chamber 92 b isprovided with a gas absorbent 95 disclosed in Japanese Unexamined PatentPublication No. 09-104487 formed in sheets or contained in a gaspermeable bag. Such a gas absorbent 95 is particularly preferable whenthe contents charged in the chamber are the first agent of hair dyecontaining stabilizer such as ammonia etc. or the second agent of hairdye containing oxidizer such as hydrogen peroxide. When oxygen generatedby dissolution of hydrogen peroxide or ammonia gas generated fromammonia pass through the inner bag 92 and out in the space between theinner bag and the outer container 91, the oxygen and the ammonia gas isabsorbed. Therefore, rise of the inside pressure of the outer containercan be prevented. Further, deterioration of the contents and corrosiondue to the generated gas can be prevented. The gas absorbent 95 can becoated inside of the inner bag 92. In this case, the gas stored insideof the inner bag without passing through the inner bag can be absorbed.However, it is more effective to coat outside. In the case of coatinginside, the surface of the gas absorbent will be covered by liquid,therefore contact area of the gas with the gas absorbent decreases andthe gas absorbing action will be disturbed. In addition, the gasabsorbent can be provided on the shoulder part or on the periphery ofthe one side of the chamber. And it can also be provided on the wholeouter surface of the inner bag 92 or on the inside of the outercontainer 91. Furthermore, the gas absorbent sacked in a gas-permeablebag can be accommodated in the outer container. Gas absorbing sheets canbe used as an intermediate layer of the inner bag described in theJapanese Utility Model No.1993-34780. Furthermore, a safety valve ormechanism to release the gas outside when the inner pressure of theouter container reaches a constant pressure can be provided. As such amechanism, the fitting structure of a cap member disclosed in theJapanese Unexamined Patent Publication No. 7-104381 or the shape of themouth part or mounting cup disclosed in the Japanese Unexamined PatentPublication No.8-149382 may be used. In this case, when the gasexceeding the amount absorbable by the as absorbent is generated, orwhen the gas absorbent does not absorb the given amount of the gas,blasting off of the valve due to the abnormal rise of the pressure inthe outer container may be prevented. As described above, a check valvecan be provided in the inner bag disclosed in Japanese Unexamined PatentPublication No.8-133359. This check valve allows the stored gas thatdoes not pass through the inner bag to flow from inside of the inner bagto outside, thereby prevent the expansion of the inner bag and burst ofthe inner bag due to the expansion.

The valve 93 is provided with a cylindrical housing having a projectionradially-outwardly protruding at the upper end; and a mounting cupfixing the housing with clipping the projection in between the openingof the outer container, covering the opening of the outer container 91,and the crimping the concave groove 91 a to make the outer containerair-tight. The other compositions are practically same as the valve 13in FIG. 2 b. Inside of the housing and the upper chamber 92 a arecommunicated through the communicating hole 97 b formed in side wall ofthe housing, and inside of the housing and the lower chamber arecommunicated through the dip tube 28 intervened by the communicatinghole 97 b of the lower end of the housing. The diameter of the dip tube28 is slightly larger than the small constriction part 94 of the innerbag 92, thereby enabling the blocking of the lower from the upperchamber of the inner bag by inserting the dip tube 28 into theconstriction part 94. The length of the dip tube 28 is not restricted,but it is preferable to be so long as to reach the bottom of the aerosolcontainer 90 so that the path is secured when the inner bag 92 iscrinkled according to decrease of the contents. The strength of theconstriction part 94 can be made stronger than the other portion and thelength of the dip tube 28 can be made so long that the lower end islocated around the constriction part. In this case, the configuration ofthe inner bag 92 is preferable to crinkle in the order from the bottomto the constriction part along with the decreasing of the contents inthe lower chamber 92 b. In this embodiment, a lip seal same as the lipseal 71 a shown in FIG. 12 e can be also provided in the constrictionpart 94 making stronger sealing between the upper and the lower chamber.The other compositions are same as the aerosol container 75 a shown inFIG. 12 c obtaining the same action.

In the embodiments disclosed above, a space 96 shown in FIG. 23 isprovided between the upper and the lower chamber except for thecontinued portion engaging with the partitioning. More specifically,there are contents inclined to pass through the synthetic resin sheetscomposing the inner bag, and these contents may pass through the innerbag to react with other contents and deteriorate the contents in thecase that only synthetic resin sheets compart the contents as thepartitioning. However, in the container described above, the contentsmay pass through the sheets composing the bag, but the space 96 preventsthe contents to pass to the other chamber where the other contents arecharged. Because the contents cannot contact directly to the inner bag(other chamber) in which the other contents are charged. Further, thesimultaneous use of the above described gas absorbent enhances theeffect of preventing the permeation. Use of a partitioning having highbarrierhood to gas is preferable.

The aerosol container 120 of FIG. 24 has a charging valve 121 to chargethe propellant at the bottom of the outer container and an inner bag 122(Japanese Unexamined Patent Publication No. 2000-24557) hung withclipping between the opening of the container body with the valve andformed so the lower end of the inner bag does not contact to the bottomof the container body. The inner bag 122 is divided into the upper andthe lower chamber by the constriction part 71 at the center, and theconstriction part 71 is provided with the same partitioning member 72shown in FIG. 12 b. Further, the inner bag 122 is provided with a foldline 123 formed along axial direction and is composed so as to be foldedand crinkled along the fold line according to discharge amount of thecontents. In this aerosol container 120, each content is charged intothe upper and the lower chamber of the inner bag 122 and the valve 124is fixed. After that, the propellant is charged from the charging valve121 to obtain the aerosol products. As well, in this embodiment, thevalve is been fixed by replicating or folding the upper end of theopening of the container body inside (Japanese Unexamined PatentPublication No.2000-628790).

The aerosol container 130 of FIG. 25 has container body 131 composed ofthe bottom 132, the body 133, and the head 134, and is formed in threepieces can by double wind up. The inner bag 135 is composed so as to besuspended or hung at the opening of the container body. The aerosolcontainer 130 has the container body 131 which is formed by winding themdoubly to form three pieces can, and has the inner bag 135 composed soas to be suspended at the opening of the container body. The inner bag135 has the constriction part 71 at its center, and the partitioningmember 72 equipped with the dip tube 28 is engaged to the constrictionpart. Further, on the partitioning member 72, the dip tube 28 isinserted, and a cylindrical gas-purging member 136 having plural sharpblades outward in radial direction is provided. The gas-purging member136 is jointed up with the center part of the partitioning member 72 byinserting together with the dip tube 28. this gas-purging member 136breaks the inner bag by deflation of the inner bag, when almost all thecontents are discharged and the inner space of the outer container andthe inner space of the inner bag communicates. After all the contentsare discharged, further opening of the valve allows the propellant inthe space of the outer container to naturally exhaust outside.Therefore, it is not necessary to take particular measures such asdischarging gas by punching a hole in the outer container after use.This aerosol product is safe and preferable for the recycling. Thegas-purging member 136 can be integrally molded with the partitioningmember 72 using synthetic resin. The gas-purging member, shown in FIG.1,5 of Japanese Unexamined Patent Publication No. 1997-267876, thegas-vent structure shown in FIGS. 1, 3, 4, 5, 6, 7, and 8 disclosed byJapanese Unexamined Patent Publication No. 1998-310111, the gas-venttool shown in FIG. 1, 3, 4, 6, 7, 8, 9, 10, 11, and 12 disclosed byJapanese Application Laid Open No.1999-171268 can be used as the aerosolproduct of this invention.

In the embodiment described above, aerosol products in which the insidepressure of the container is increased by a propellant such ascompressed gas. The container 100 shown in FIG. 26 employs pumpingmechanism 101 as a means for pressurizing the inner bag. The valve 101 aprovided with this pumping mechanism 101 is composed of a housing 102, astem 103 accommodated in the housing, a spring 104 a always energizingthe stem upward always, a piston 104 accommodated in the housing andserving as a check valve, communicating holes 103 a, 103 b provided atthe lower end of the housing 102, and check valves 106 a, 106 b forclosing the communicating holes 103 a, 103 b. These check valves 106 a,106 b are same as the check valve 51 a shown in FIG. 3 a, and arecomposed so that the communicating holes 103 a, 103 b are closed withballs energized by springs toward the communicating holes 103 a, 103 b.The stem 103 and the piton 104 are conventional and publicly known, anda push button is mounted on the upper end of the stem 103. The dip tube28 is attached to the communicating hole 103 a, thus communicatecommunicates hole with the lower chamber.

Other components such as the inner bag and the outer container are sameas those shown in FIG. 2 or FIG. 23 etc, By pushing down the pushbutton, the piston 104 comes down and an amount for a single usage ofthe contents is discharged into the housing 102 by the action of thecheck valve. After that, the push button goes up by the spring 104through the stem 103. In this going up, the first and the second pistonnot shown in the figure also goes up to updraw the contents into thehousing 102 for next discharge through the lower end check valve 106 a,106 b. The use of the container having such pumping mechanism enables touse two different contents leaving no residue in the inner bag.

FIG. 27 shows an embodiment of a squeeze bottle type container pushingout the contents directly. The container 110 is provided with a flexibleouter container 111, the inner bag 112 having the upper and lowerchamber, and a cap 113 mounted on the opening of the outer container. Inthis container 110, the container body 111 composes the pump, and it iscomposed so that deformation due to the local force is recovered by theelasticity. In a part of the outer container 110, a hole 115communicating with outside air is formed, and the check valve 114 isprovided inside of the hole 115.

The inner bag 112 is same as that of aerosol container 90 of FIG. 23 andis divided into the upper and the lower chamber. The cap 113 is aboutchevron and made of synthetic resin having the communicating hole 115 a,115 b in its hem. The center of the communicating hole 115 bcommunicates with the lower chamber through the dip tube 28, and theother communicating hole 115 a directly communicates with the upperchamber. And the upper part of these communicating hole 115 a, 115 bcommunicates with a spout 117 through a housing mixing chamber 116. Whenthe cap 113 is fixed on the outer container and an external force Q isapplied so as to crush in a part of the container body 112, an uniformforce is applied to the whole inner bag 112, the contents enter into thehousing mixing chamber 116 through each communicating hole 115 a, 115 bfrom the upper and the lower chamber and mixed thereupon and dischargedthrough the spout 117. In the top surface of the housing mixing chamber116, the check valve 118 is provided to prevent the draw in of the airfrom the spout 117. In addition, it is preferable to provide a checkvalve in the communicating hole 115 a, 115 b at an inlet of the housingmixing chamber 116. In this case, the contents mixed in the housingmixing chamber 116 is prevented to flow backward. The length of the diptube 28 can be as long as to reach the constriction part or the lowerend of the container body.

FIG. 28 shows the embodiment of the container 140 which pushes out thecontents by the elasticity of the inner bag itself. The container 140 iscomposed of the valve 141, the inner bag 142 made of elastic materialsuch as synthetic rubber or silicone rubber, the body that accommodatethe inner bag and engaged with the valve 141 at its opening, and the capwhich fixes them. The inside layer of the inner bag is laminated by aprotection layer to prevent erosion. The inside surface of the inner bag142 sticks to each other leaving no space in the natural state (elasticenergy being zero). The inner bag is inflated by charging in thecontents (elastic energy being stored). Therefore, release of the valvemakes discharge of almost whole contents. The valve is securely fittedto the opening of the inner bag to enclose the contents. The valve 141is conventional and publicly known. The outer container of thiscontainer 140 is not necessary when the valve and the inner bag aretightly sealed. In this case, the inner bag serves as the outercontainer and the pressuring means. In this case the opening of theinner bag 142 can be tightly fastened using metal wires. On the otherhand, elastic rubber belts may be wound around the perimeter of theupper and lower chamber of the flexible inner bag.

The aerosol container 170 of FIG. 29 has the valve 171, the inner innerbag 172 of which upper end is connected to the valve, the outer innerbag 173 to accommodate the doubled inner bag, where the outer inner bag173 corresponds to the inner bag of this invention and the doubled innerbag 172 corresponds to the partitioning comparting the outer inner bag173. However, the partitioning member described above does not transmitthe pressure between the upper and the lower chamber, the inner innerbag 172 transmits the pressure between the upper and the lower chamber.As the valve, that of valve 13 b, 13 c or 13 d shown in FIG. 3˜FIG. 7 isused. These valves have the communicating hole 48 a at their lower endand have the communicating hole 48 b at their upper side end. The innerinner bag 172 is mounted so as to cover the housing and not to close thecommunicating hole 48 b, and communicates with the valve through thecommunicating hole 48 a. The outer inner bag 173 communicates with thevalve through the communicating hole 48 b. Then the opening of the valveallows contents of the outer and the inner inner bag to flow into thevalve. In order to make the seal between the inner inner bag 172 and thevalve, sealing means such as O-rings can be used between the inner innerbag 172 and the valve. The production method of this aerosol product isdescribed bellow. The contents of the doubled inner bag 172 and theouter inner bag 173 accommodated in the outer container are charged byseparate lines, the inner inner bag 172 is fixed to the valve, and thenthe valve is inserted into the outer inner bag 173. The propellant ischarged, and the valve is fixed. The inner bag can be previously fixedto the valve and contents can be charged from the valve.

As described above, in the case that the outer container is nottransparent, it is preferable to provide a means to check the residualamount of the contents. As a means for checking the amount of theresidual, for example, like the container 181 shown in FIG. 30, acomb-shaped discharging member 181 a is provided. A catch 182 isprovided on the shoulder part of the container 181. As other structuresof the container, any one of the embodiments described above can beused. When the container 181 is hanged by picking up the catch withfingers, bars, or threads, the container 181 inclines according to theamount of the contents left in the inner bag. Previous description ofthe relation between the inclination and the remaining amount of thecontents is written on the outside surface of the container or in theinstruction book attached separately enables to confirm the remainingamount of contents in the container 18 easily.

Further, the container 183 shown in FIG. 31 has a cylindrical containercover 184 with bottom that can accommodate the container 183 and has ascale on the periphery surface. The other configurations aresubstantially same as the container 181 without the catch of FIG. 30.

The confirmation method of the residual amount in the container 183, aliquid such as water is charged into the container cover 184, and thecontainer 183 is floated in the container cover 184. The level (height)of the container 183 differs according to the buoyancy of the container.And the buoyancy differs according to the residual amount of thecontainer 183. So, the residual amount of the container 183 may beconfirmed by previously recording the relationship between the level ofthe container and the residual amount on the periphery surface or in theattached documentation. For example, the container 183 equipped with thescale that shows the relationship between the protrusions height of thecontainer 183 from the container cover 184 and the residual amount maybe mentioned. Such as, the container 183 equipped with the scale written100 on the periphery surface 5 cm below the upper end of the container183 maybe used to the container in which the upper end of the container183 protrudes 5 cm above the top of the container cover 184 when thecontainer 183 with residual amount 100% is inserted into the containercover 184 with water charged.

Further like shown in FIG. 32 a, a dispenser with cover member 185 thatcovers the container 185 and spring balance scale 187 having spring atthe top of the cover member 185 may be used. In the cover member 185, acabinet 188 that accommodate the spring balance scale 187 and the knob189 formed at the top of the spring balance scale are provided. Theother configuration is substantially same as the container 181 of FIG.30. The spring of the spring balance scale extends when the container185 is suspended by the nipping the knob 189. Therefore the residualamount of the container may be confirmed by previously recording therelationship between the extension amount of the spring and the weightof the container on the scale of the spring balance scale or in theattached documentation. In this embodiment the dispenser with the springbalance scale was disclosed, but this is not limited and may besubstituted by balance scale using elasticity such as rubber balancescale.

A container 185 a shown in FIG. 32 c is provided with a spring balancescale 187 a with a spring 186 a attached to the bottom of the containerand has a cabinet 188 a that accommodate the spring balance scale 187 a.The other configuration is substantially same as the container 185 ofFIG. 32 a.

A dispenser having a means to check the remaining amount of the contentscan confirm the residual amount of the container even if the containerbody is not transparent or translucent. Thus the problem of notobtaining the desired effect or finish, due to the running down of thecontents during the use can be solved.

A discharging member that can be used to the aerosol product of thepresent invention is disclosed in FIG. 36 a. This discharging member 200is preferably used in the aerosol product that comprises the valve 13 bof FIG. 5 b that dispense the contents of the upper and lower chamberwithout mixing each other. The discharging member 200 is cylindrical andhas a stem engaging 201 that engage with the stem 14; a nozzle 202 thatsimultaneously dispense the contents A, B supplied from the stem;passages 203 a, 203 b of the discharging member that communicate thestem engaging 201 and the nozzle 202 and where the contents A, B flows.

The nozzle 202 is cylindrical having bottom and is provided with theinjection hole 202 a at the center of the bottom, and engages with adischarging member body 204. Further, whorled projection 208 that whorlfrom the edge to the center is formed at the inner side 206 of thebottom, and is formed on the engaging surface between the dischargingmember body 204 and the nozzle 202. Further, an opening of the passage203 a, 203 b belong to the edge of the inner side 206 of the bottom whenthe nozzle is engaged with the discharging member body 204 like shown indotted line (FIG. 36 b).

Therefore, the contents A, B that are dispensed from the passage 18 a,18 b of the valve reach the inner side of the bottom 206 through passage203 a, 203 b of the discharging member. As a result, the contents formthe volute due to the projection 208 and are mixed at the inner side 206of the bottom. And the mixed contents discharge from the injection hole202.

The discharging member 200 is best suiting for the contents with lowviscosity, with liquid form, that discharged in the state of mist, andthat reacts when the two liquid are contacted or mixed. Therefore themixture of the effect is large, and the effects can be obtainedsimultaneously at the time of discharging. For example, by using thecontents that carry out neutralization and thickening at the time ofmixture, the mixed content starts increasing the viscosity at theinjection hole, discharges in rough misty state, and becomes gel state(gelatinous) at the adhesion surface thus prevent the drop off. Further,when the contents that dissolute and carry out exothermic reaction orendothermic reaction by mixing the contents are used, the dischargedcontents are injected with form of mist in warm or cold state.

The other type of discharging member for the aerosol product for thisinvention is disclosed in FIG. 37. Like the discharging member of FIG.36, this discharging member is preferably used in the aerosol productthat comprises the valve in which the contents of the upper and lowerchamber are dispensed without being mixed with each other. Thedischarging member 211 is provided with two nozzle 205 a, 205 b havinginjecting hole 202 a, 202 b respectively and a discharging member body204. These two injecting holes 202 a, 202 b have injecting angle thatcrosses with each other. Therefore the contents that are discharged orinjected using the discharging member 211 are mixed with each other atthe space near the injecting holes. Thus the contents starts reactingwhen the contents are at the space between injection hole and thetarget, or when the contents adhere at the target, and user may obtainthe effect soon after the injection.

The nozzle 205 a, 205 b are engaged with the discharging member body 204in the above disclosed embodiment, but it may be integrally formed.

The other discharging member is disclosed in FIG. 38. Like thedischarging member 211 of FIG. 37, this discharging member discharge orindependently inject the contents that are separately supplied. Thedischarging member 215 is provided with a discharging member body 204that independently flows the contents A, B supplied separately from thevalve through passage 203 a, 203 b of the discharging member; and anozzle 202 inserting into a nozzle loading slot 216 of the dischargingmember body. The discharging member 215 has central injecting hole 202 aand three outer injecting hole 202 b formed on outer periphery of thecentral injecting hole 202 a at even intervals. The central injectinghole 202 a is circular and formed at the center of the nozzle, and iscommunicated with passage 203 a of the discharging member. The groove217 is formed at the inner surface of the nozzle loading slot 216 inaxial direction and the groove 217 is communicated with passage 203 b ofthe discharging member. The slit between the groove 217 and the nozzle202 forms the outer injecting holes 202 b. The number of the outerinjecting holes are not limited and maybe formed within from 2 to 10holes. Thus, the discharged contents discharged from the dischargingmember 215 forms a stripe. The contents with high viscosity arepreferable for aerosol product with the discharging member 215.Therefore, the contents discharged with stripe may be mixed by otherforce such as by hand. Further, for the contents A and B, the gel state(gelatinous) content and the mousse state content maybe used. And byconnecting the container of the present invention with the dischargingmember 215, so as to make the gel state content injects from injectinghole 202 a through passage 203 a of the discharging member and themousse state content injects from injecting hole 202 b through passage203 b of the discharging member, the discharging contents of the gelstate contents wrapped by the mousse state contents may be obtained.

Here, the preferable figure of the inner bag to charge two kinds of thecontents are disclosed in FIG. 39.

The inner bag 220 is cylindrical with bottom and has body 224 having anupper chamber 221, lower chamber 222, and constriction part 223 betweenthe upper and lower chambers; neck part 225 formed on the top of thebody in which the flange 225 a is formed on the upper end; and a bottompart 226 that closes the lower end of the body.

The constriction part has a diameter smaller than the body and the upperchamber 221 and the lower chamber 222 are formed in tapered shape towardthe constriction part. Therefore the residual of the contents may beminimized, because the upper and the lower chamber 221, 222 deflateseasy along with the discharging of the content. Further, the lower partof the lower chamber 222 is tapered toward the bottom 226 as the bottomarea may decrease. This will ease the insertion of the inner bag intocontainer body.

Further, thickness of the constriction part is formed thicker than theother part of the inner bag. This will increase the strength of theconstriction part. So, when the partitioning member is inserted into theconstriction part, the constriction part will closely engage with thepartitioning member and avoid the omission of the partitioning memberfrom constriction part.

The inner bag 220 is manufactured by blow forming method using thetubular synthetic resin and the bottom is formed by pasting the insidesurface of the tube. So the continuous production can be achieved, thusincrease the working efficiency. However, when the contents generate agas or include gas, the gas may percolate through the joint surface ofthe bottom. Either a resin sheet may be adhered or a gas absorbent coat227 made of gas absorbent may be equipped under the bottom 226 forpreventing the percolation of the gas. Especially when the gas is analkalinity gas such as ammonia gas or an oxidizing gas such as oxygengas, the corrosion of the metal container body may be prevented due tothe percolated gas. Further as shown in imaginary line, a cylindricalgas absorbent bag that is accommodated in the container body andaccommodate whole inner bag 220 may be attached between the containerbody and the valve.

In the inner bag mentioned above, because plural of different contentsare charged, the inner bag must be stable against all contents. The word“stable” means in the above is that the dispenser as a whole is stableand that the inner bag is anticorrosion against the contents andprevents the percolation of the gas generated from the contents such asdecomposition.

In such an inner bag, for example, materials stable against the contentscharged in each chamber laminated on the each chamber respectively maybementioned. More, the material stable against the content charged in oneof the chamber is laminated as a film on the outer surface or the innersurface of the other chamber of the inner bag made of material stableagainst the content charged in the other chamber maybe used. Further,the inner bag that is provided with the upper chamber member 85 a andthe lower chamber member 85 b, like the inner bag 85 of FIG. 20 a, andthe each chamber members are formed with the material that is stableagainst the contents that are to be charged maybe used.

For example, the two layer structure inner bag 230, shown in FIG. 40 a,may be used in the aerosol product comprising the inner bag having theupper and lower chamber, and the upper chamber is charged withalkalinity contents and the lower chamber is charged with oxidizingcontents. The inner bag 230 is provided with the inner layer 231 (alkaliproof layer) made of high alkali proof material, and the outer layer 232(acid proof layer) made of high acid proof material laminated on outsidesurface of the inner layer. The material of the inner and outer layermay be reversed. This structure will prevent the inner bag from blastingdue to the corrosion of the inner bag against the contents. Further, thecorrosion of the container body due to the percolation of the acidcomponent or the alkaline component may be prevented. Also deteriorationof the content due to the percolation of the contents of the otherchamber may be prevented.

The inner bag 234 of FIG. 40 b may be used. The inner bag 234 has a film236 made of high alkali proof material laminated on the outer surface ofthe upper chamber 221 of the inner bag body 235 in which is made of highacid proof material. The film 226 is laminated on the outer surface ofthe lower chamber 222, when the alkaline content is charged into thelower chamber. The film may be laminated during the manufacturingprocess of the inner bag or the film may be covered to the inner bag bypasting or by heat contraction.

As the material with high acid proof, polyester such as polyethyleneterephthalate, polylefins such as polythene and polypropylene, andpolyvinylidene chloride may be mentioned. As the material with highalkali proof, polyamide such as Nylon 6 and MXD-6, polyphenylen sulfidesmay be mentioned.

Further, gas barrier layer 240 may be laminated on the chamber thatcontains contents generates gas like shown in imaginary line on thechamber of the inner bag 230, 234. For example, as the material suitableto prevent the percolation of the ammonia gas generated from thealkaline liquid containing ammonia or oxygen gas generated from the acidliquid containing hydrogen peroxide, ethylene-vinylalcohol copolymersand polyvinylidence chlorides may be mentioned. The gas barrier maybeformed by providing gas barrier layer between the acid proof layer andthe alkali proof layer to form three layer structure, or by providingthe gas barrier layer on the both side of the laminated layer of theacid proof layer and alkali proof layer to form four layer structure, orby providing the gas barrier layer on both side of the three structurelayer of the above to form five layer structure. Further, silica oraluminum may be distributed on the otter surface of the inner bag bydeposition to further improve the quality of the gas barrier.Especially, when the silica is distributed the resistance against theacid and the alkaline also improves.

Therefore, the inner bag with gas barrier can prevent the percolation ofthe ammonia with time and prevent the degradation of the ammoniaconcentration. As a result, the degradation and decomposition of thecomponent that is composed with the ammonia and is stabilized by theammonia may be prevented. Further, the degradation and decomposition ofthe contents that are charged in other chamber may be prevented.
